Opinion REYNOSO,J. This is an automatic appeal (Pen. Code, § 1239, subd. (b)) after defendant was sentenced to death for robbing and shooting two putative confederates in a drug trafficking scheme, one fatally. He was found guilty by a jury of two counts of robbery (§ 211), one count of attempted murder (§§ 187, 664) and one count of first degree murder with a special circumstance, i.e., murder in the commission of a robbery (former § 190.2, subd. (c)(3)(i), as enacted by Stats. 1977, ch. 316, § 9, pp. 1257-1258, repealed by Prop. 7 of the initiative measure approved by the voters Nov. 7, 1978). Allegations that defendant personally used a firearm in the commission of one of the robberies, the attempted murder, and the murder were found to be true. (§ 12022.5.) After careful review of each of defendant’s arguments, we affirm the judgment on the guilt phase and the special circumstance finding. However, we reverse the judgment on the penalty phase because (1) the trial court failed to give a reasonable doubt instruction regarding evidence of other criminal activity, and (2) the trial court failed to limit admissibility of criminal activity to evidence that demonstrates the commission of an actual crime. Facts Defendant became acquainted with Bruce Bartulis (the robbery and murder victim) and Ronald Rose (the robbery and attempted murder victim) in September of 1977. Rose and Bartulis, who were in the construction business, began building some houses adjacent to defendant’s home in Newport Beach, California. The three men became friendly after defendant allowed the builders to use an electrical outlet located on his premises. On the first day of November 1977, defendant offered Rose and Bartulis an opportunity to participate in a large cocaine purchase, proposing that they invest $25,000 and promising them a return of five times their investment. Rose and Bartulis accepted, and, on November 2, Rose cashed a check for $10,000 and gave the money to defendant. On several occasions thereafter, defendant prodded them “to come up with the rest of the money.” Rose subsequently gave defendant a check for $1,500, but eventually told defendant that they could not deliver any more cash and asked him either to use the amount they had given him or to return the money. Defendant agreed to use the money. In late November or early December 1977, defendant indicated to Rose and Bartulis, who had told defendant of their difficulties in obtaining insulation for the houses they were constructing, that he knew where they could obtain some stolen insulation, since “his brother was a part of this deal.” In fact defendant has no brother. Defendant told the builders that they would have to pick up the insulation in Fresno, where it was being stored in a warehouse. Rose and Bartulis agreed to buy some of the insulation. On the morning of December 7, 1977, defendant informed Rose that the insulation was available to be picked up that night in Fresno. Rose had notarized and given defendant a promissory note for $25,000, which represented the balance of the $25,000 Rose and Bartulis had committed themselves to in the cocaine deal as well as payment for the insulation. Defendant told Rose that they should meet him that evening at a gasoline station just off the freeway, and instructed him to “get as much cash together as [he] could.” Rose obtained between $3,500 and $5,000 in large-denomination bills. With that in hand, he and Bartulis drove to Fresno in Rose’s 1977 Ranchero. Rose had an unloaded .44 magnum pistol in the vehicle, with some ammunition behind one of the seats. They checked into a motel designated by defendant and then went to the gasoline station at the appointed time. Within half an hour, defendant arrived, accompanied by his girlfriend, Sharon Col-man. Colman had been living with defendant since October and was acquainted with Rose and Bartulis. That day she had flown from Newport Beach to Fresno. She then called defendant, who had flown to Sacramento, and arranged to have him pick her up at the airport in Fresno. Defendant arrived at the airport about 11 p.m., driving a Toyota he had borrowed from his mother (who resided in Sacramento). He told Colman that they were going to meet Rose and Bartulis at a gas station. Defendant and Colman met Rose and Bartulis at the gas station about 11:30 p.m. Defendant directed the builders to follow him to where they would meet his brother. They followed as defendant and Colman drove north on Highway 99. In the course of the drive, they stopped at an open gasoline station, where defendant used the restroom. When he came out, he walked over to the Ranchero and borrowed a book of matches. The four then continued their trip. Eventually, defendant exited the freeway and the vehicles stopped in a vacant area off the road and just east of the off-ramp. Defendant got out of the Toyota and walked over to the driver’s side of the Ranchero (which was parked alongside). While Colman sat in the Toyota listening to the radio, the three men talked for a while, drank some beer and smoked a marijuana cigarette. At one point, defendant re-entered his car on the passenger side, continuing his conversation with Rose and Bartulis. The tenor of the conversation was not angry. A few minutes later, defendant again exited the car and stood next to the Ranchero. Defendant leaned inside the driver’s window. Suddenly Colman heard shots being fired. She saw gunflashes and, as defendant withdrew his arm from a window, saw a gun in his hand. She heard the driver, Bartulis, moaning; defendant silenced him by striking him over the head with the gun. Defendant leaned Bartulis forward and extracted his wallet, then went around to the other side of the Ranchero and did the same to Rose. In the course of this search, he complained that he could not find the money they were supposed to have. He returned to the Toyota with the two wallets and two handguns (the one he had used in the shooting and another) and handed them to Colman. Defendant had Colman open the trunk of the car, from which he took a can of gasoline. He then poured the gasoline over the Ranchero and its occupants and set them ablaze. Rose was still alive. After being shot, Rose had “played possum” while being searched and even while gasoline was poured over him. As with the shooting, he did not actually see defendant do either of these things. He did recall that defendant was alone at the window on the driver’s side, that the shots came from the direction in which defendant was standing, and that he heard a male voice close to him while his body was being searched. When he was set afire, Rose jumped out of the Ranchero and tried to shed his burning clothing. Defendant, who had run back to the Toyota and begun to turn it around, saw Rose running away. Complaining to Colman that Rose “wasn’t dead,” defendant drove at Rose and hit him, in the process cracking the windshield. Defendant and Colman drove to Sacramento. He was calm, though somewhat disturbed at not knowing whether Rose was dead. He lamented several times that he had been unable to find the money that Rose was supposed to have had with him. (The wallets, which Colman handed over to defendant in the car, contained only $120 to $150.) Defendant also commented that his gun “was too big of a calibre because he was too close.” Upon reaching Sacramento, the pair went to the home of defendant’s mother. Defendant went to his mother’s room and told her he had been to a “disco” dance and that on the way home the windshield had been cracked by some gravel thrown up by a truck. He assured her he would “take care of it” that day. A short time later, hearing voices downstairs, defendant’s mother came downstairs to investigate. Though she had originally thought her son was alone, she saw a woman (presumably Colman) with him. Meanwhile, two Madera County Deputy Sheriffs proceeding along Highway 99 on a routine patrol noted a glow in the sky which turned out, on closer inspection, to be three fires just off the freeway. The deputies ran to Rose and covered him, extinguishing the flames. Rose had suffered five gunshot wounds and bums over 65 percent of his body. When he was taken to the hospital, it was not thought that he would live. In the Ranchero, Bartulis was found dead, with a bullet wound in the heart. He appeared to have been shot in the left side of the chest and the wound indicated that a large—.44- or .45-calibre—bullet was used. Two bullet holes were observed in the Ranchero, and a spent .45-calibre shell was found on the ground near the vehicle. The deputies also found a jacket containing badly burned currency showing $100 denominations. The day after the killing, Colman flew to Fresno. Defendant remained in Sacramento for a few days. While Colman was in Fresno, defendant told her on the telephone that he had had a friend call the hospital and learned that Rose was in “really bad condition,” that he “didn’t remember a lot of things” and “couldn’t talk or anything.” Defendant visited Colman in Fresno and then they rejoined each other in Los Angeles; from there they drove to Salt Lake City, where Colman had relatives. On December 14, 1977, a warrant issued for defendant’s arrest; an arrest warrant was also apparently issued for Colman. Colman later left Salt Lake City, apparently in the latter part of December 1977, and returned to Sacramento in the car defendant had borrowed from his brother-in-law. Defendant arranged to have Colman stay at a motel in Sacramento and await contact from a friend of his. Instead, Colman took the opportunity to turn herself in, despite defendant’s expression of confidence that “she would not be dumb enough to cross him or call anybody about it, because if he was in a situation where he couldn’t get to [her], that he would have somebody else that could.” Defendant was apprehended by the Federal Bureau of Investigation on March 17, 1978. The defense was alibi. Defendant primarily sought to persuade the jury that Colman and Rose and defendant’s erstwhile friend, Richard Graybill (who aided police in their efforts to apprehend defendant) were involved in a conspiracy to fix defendant with the blame for the shootings, which were purportedly committed by Graybill and Colman. Rose’s participation in the conspiracy, it was suggested in argument, might be explained by a desire to avoid the necessity of paying off the $25,000 note or to avoid criminal liability for shooting Bartulis himself. Defendant admitted knowing Rose and Bartulis. With regard to the cocaine deal, he testified that he set up a meeting for certain individuals interested in consummating such a transaction, using a large barbecue party as a “front.” These individuals, including Rose and Bartulis, had expressed interest in using defendant’s South American “source” and his “transportation supplies” to bring cocaine into the country. Defendant did not attend the meeting himself, but understood that there were six shares taken by investors at $35,000 a share. Richard Graybill was the “coordinator” of the deal, though the money was ultimately to go to defendant’s source in Peru (whom he refused to name). After putting up $10,000 in “front money,” Rose and Bartulis had difficulties and were unable to come up with the remaining $25,000. Because he had vouched for them as being “cool” to the other participants (essentially “co-signed for them”) defendant agreed to lend them $25,000 in exchange for a promissory note and the use of their contractor’s license. When Rose indicated to defendant that part of their business difficulties stemmed from the unavailability of insulation, defendant told Rose that Graybill was in the building supply business in Fresno and put Rose in contact with him. Defendant testified that he was at a business meeting and then a disco in Sacramento on the night the killing took place, though he refused to divulge the identities of the people at the meeting. Graybill came to the motel in Sacramento where defendant’s meeting was taking place and asked to borrow his (defendant’s) mother’s car. Defendant lent him the car and, at about midnight, drove Graybill’s Cadillac from the motel to a disco and then home. Graybill, accompanied by Colman, returned the Toyota with a damaged windshield between 4:30 and 5 in the morning, without explanation. Defendant had the windshield replaced the next day. When he left the state after the killing, defendant, assertedly, had already agreed with Graybill to “ride the beef for him,” since defendant “had been to prison” and Graybill “had some very bad enemies” from his prior narcotics dealings. They decided defendant should go to Salt Lake City to “let things cool off” while Graybill negotiated on his behalf to give himself up and plead guilty to second degree murder. Discussion I. Guilt Phase. We first review the claims of error relating to the guilt phase of the trial. A. Defendant waived the public defender’s conflict of interest in representing him at his preliminary hearing. Defendant contends that he was deprived of the effective assistance of counsel at his preliminary hearing, since his counsel, the public defender, had represented Colman at an earlier stage. This contention is without merit. The record reflects that defendant knowingly waived any objection to the conflict, after his motion for substitution was granted based on his own assertion that a conflict existed. At a hearing on his motion for a continuance of the preliminary hearing on June 21, 1979, the public defender represented to the court, for the record, in defendant’s presence, that he had explained to defendant that his office had represented Colman, and that “we did talk to her [and] ... did have information from her.” He had further explained, he said, that defendant could, if he wished, “declare a conflict,” but that defendant had indicated that he wished to be represented by the public defender “at these stages of the proceeding.” Counsel noted that defendant might still wish to “declare” a conflict before the preliminary hearing. Defense counsel’s remarks later in the hearing indicate that defendant had been encouraged to and expected to retain other counsel in the future. Defendant remained silent throughout. He was indeed represented by the public defender at the preliminary hearing. Later, however, on October 30, 1979, defendant moved for substitution of his counsel, declaring as his reason the public defender’s conflict of interest. The next day, the court heard the motion and relieved the public defender and appointed new counsel. Defendant’s silence in the courtroom on June 21, 1979, in the face of his counsel’s representations, does not show an unambiguous and knowledgeable waiver of the right to effective counsel as contemplated by our decisions; an effective waiver, under these decisions, must be express and understanding, in response to specific advice by the court regarding the potential conflict and the right to new counsel if a conflict exists. (See In re Hochberg (1970) 2 Cal.3d 870, 878-879 [87 Cal.Rptr. 681, 471 P.2d 1]; People v. Chacon (1968) 69 Cal.2d 765, 11A [73 Cal.Rptr. 10, 447 P.2d 106, 34 A.L.R.3d 454]; In re Johnson (1965) 62 Cal.2d 325, 334-335 [42 Cal.Rptr. 228, 398 P.2d 420]; People v. Angulo (1978) 85 Cal.App.3d 514, 518-519 [148 Cal.Rptr. 517]; see also United States v. Garcia (5th Cir. 1975) 517 F.2d 272, 278 [requiring advice as to dangers of conflict and a narrative response by defendant].) However, defendant’s failure to move to set aside the information under section 995, after his substitution motion was granted, bars him from raising on appeal his challenge to the conduct of the preliminary hearing. (§ 996; People v. Pompa-Ortiz (1980) 27 Cal.3d 519, 529 [165 Cal.Rptr. 851, 612 P.2d 941]; People v. Harris (1967) 67 Cal.2d 866, 870 [64 Cal.Rptr. 313, 434 P.2d 609]; People v. Palacios (1968) 261 Cal.App.2d 566, 571-572 [68 Cal.Rptr. 137].) Defendant cites People v. Anderson (1968) 70 Cal.2d 15 [73 Cal.Rptr. 550, 447 P.2d 942] for the proposition that “[sjection 996 does not express an absolute mandate, however, and cases may arise in which a defendant may properly attack his indictment for the first time on appeal. Section 996, like the general rule that errors not objected to at trial cannot be raised on appeal, rests upon waiver. Thus, if the circumstances do not show a waiver, a defendant may challenge the indictment on appeal even though he did not raise the point by a motion under Penal Code section 995.” ( {Id., at p. 23.) The circumstances of this case, however, do show a waiver. Although defendant points to the fact that his motion for substitution of counsel was in propria persona and attempts to suggest that the conflict of interest was “overlooked by the experienced trial counsel and the court itself,” the record establishes beyond any doubt that, after his motion for substitution was granted on October 31, 1979, defendant knew the public defender had a conflict of interest owing to its prior representation of Colman, which entitled defendant to new counsel. In his reply brief, defendant argues that the record does not show whether he was informed that in the course of its representation of Colman, the public defender’s office entered into an agreement with Colman whereby she told the prosecution her story under an informal testimonial immunity arrangement. This possibility makes no difference. What was important to defendant’s understanding of the conflict was the knowledge that Colman had given information about the crimes to her public defender in the context of an attorney-client relationship, and this posed possible problems in cross-examining Colman. Though it may seem anomalous to conclude that there was no valid waiver of defendant’s right to counsel by his silence at the June 21, 1979, hearing, but that his silence after the substitution motion was granted did constitute a waiver, the record shows that at the latter time defendant knew all that the requirement of an express waiver is designed to assure that he knows. Accordingly, no reason appears for interfering with the normal operation of section 996. B. The trial court’s error in refusing to order disclosure of any agreement between the prosecution and Colman ’s attorney in exchange for Colman ’s testimony was harmless beyond a reasonable doubt. During the trial, defense counsel stated on several occasions that the prosecution and Colman’s attorney had entered into some agreement for Colman’s testimony. The trial court concluded that any agreement not communicated to Colman was irrelevant to the issue of her credibility. Thus, it prevented defense counsel from examining the prosecution and Colman’s attorney about the existence and terms of any such agreement. Defendant contends that this ruling deprived him of due process. The prosecution has a duty to disclose all substantial material evidence favorable to an accused, including evidence relating to the credibility of a material witness. (People v. Ruthford (1975) 14 Cal.3d 399, 406 [121 Cal.Rptr. 261, 534 P.2d 1341].) “[Suppression of substantial material evidence bearing on the credibility of a key prosecution witness is a denial of due process . . . .” (Id., at p. 408.) Since a witness’s credibility depends heavily on his motives for testifying, the prosecution must disclose to the defense and jury any inducements made to a prosecution witness to testify and must also correct any false or misleading testimony by the witness relating to any inducements. (Giglio v. United States (1972) 405 U.S. 150, 154-155 [31 L.Ed.2d 104, 108-109, 92 S.Ct. 763]; People v. Westmoreland (1976) 58 Cal.App.3d 32, 43 [129 Cal.Rptr. 554].) In this case, according to the testimony of Colman’s attorney and the prosecutor, no inducements to testify were communicated by them to Col-man in any manner, except that her attorney advised Colman to “have faith and trust” in her (the attorney) and testify. Colman testified that she had been charged along with defendant in connection with the murder, but was now free on her own recognizance. She confirmed that her preliminary hearing had been continued numerous times. Colman further indicated in response to cross-examination that she was “expecting that they would take into consideration that [she was] willing to cooperate.” (In fact, the charges against Colman were dismissed shortly after the trial.) Therefore, the present case differs from People v. Westmoreland, supra, 58 Cal.App.3d 32, in which the prosecutor knew that the witness’s response to a question whether he had been offered the opportunity to plead guilty to a lesser offense was false. Despite his knowledge of the witness’s misleading answer, the prosecutor in Westmoreland remained silent and failed to correct the testimony. Here, there was no attempt to mislead the jury into believing that the witness testified without any expectation of leniency. Col-man candidly admitted that she expected her willingness to cooperate to be taken into consideration by the prosecution. However, defendant argues that the prosecution and a witness’s attorney should not be permitted to insulate a witness from any agreement entered into in exchange for testimony. He insists that some notion of the possibility of leniency was communicated to Colman. Furthermore, her ignorance of possible conditions on its availability might have induced her to testify in a manner calculated to satisfy the prosecution. (See, e.g., People v. Medina (1974) 41 Cal.App.3d 438 [116 Cal.Rptr. 133] [use of witnesses’ testimony violated due process when the testimony was given in exchange for an immunity that was conditioned on the testimony’s consistency with the witnesses’ pretrial statements to police].) We find the reasoning of the Westmoreland court persuasive on this issue: “[Wjhenever the district attorney offers one of several persons accused of complicity in the same criminal offense the opportunity to plead guilty to a lesser offense or engages in discussions with his attorney concerning the possibility of leniency, and later the accused appears as a prosecution witness at the trial of the other defendants, both the witness and the district attorney are subject to the accusation that offers of leniency were made in exchange for favorable testimony. If such a charge is made at the trial, and if there is a conflict in the evidence on this issue, it is up to the jury to resolve the conflict and then to judge the credibility of the prosecution witness accordingly. To hold otherwise would lead to post-trial charges and countercharges and, what is worse, could pave the way to the type of double talk which ultimately could lead to the circumvention of the disclosure mies which have evolved to insure a fair trial to all persons accused of crime.” (Italics added.) (Id., 58 Cal.App.3d at p. 47.) In context, it seems clear that the “double talk” condemned by the Westmoreland court referred to precisely the same kind of allegedly “undisclosed” promise to a witness’s attorney at issue in this case. As Westmoreland recognized, unless the defense attorney is permitted to discover the contents of the arrangement between the prosecutor and the witness’s attorney, the defense cannot effectively challenge the witness’s statement that his testimony is not being given in return for favored treatment. If disclosure is not required, the defense will never learn whether the terms of the agreement itself suggest that the witness must have had some inkling of the arrangement—as would be the case, for example, if the promised leniency were dependent on the witness’ testifying in a particular manner. Consequently, when an accomplice testifies for the prosecution, full disclosure of any agreement affecting the witness is required to ensure that the jury has a complete picture of the factors affecting the witness’s credibility. Moreover, the “tactical” device of keeping a prospective prosecution witness in the dark about the terms of a deal that has been negotiated with his counsel suffers from an even more fundamental flaw than an impairment of defense discovery rights. As Justice Fleming pointed out in People v. Brunner (1973) 32 Cal.App.3d 908, 913-914 [108 Cal.Rptr. 501], one of the principal dangers that arises whenever an accomplice testifies in exchange for an expected benefit is that the “witness may be so influenced by his hopes and fears that he will promise to testify to anything desired by the prosecution in order to obtain a grant of immunity. Because the satisfaction of the prosecution is the [witness’s] ticket to freedom, the prosecutor, by dangling the promise of immunity, can put the words he wishes into the [witness’s] mouth. This danger is especially grave when the witness knows he is expected to give particular testimony, absent which he will not receive the promised immunity.” It is true that, unlike People v. Medina, supra, 41 Cal.App.3d 438, a witness who is kept ignorant of the terms of the bargain that his attorney has arranged with the district attorney does not know for certain that favorable treatment depends on his testifying in a particular manner. At the same time, however, unless the witness is informed both of the terms of the agreement and that his receipt of the benefit cannot be denied so long as he testifies fully and truthfully at the criminal trial, the witness cannot help but believe that his own treatment will depend on how “well” he does—from the prosecution’s perspective—in testifying against his accomplice. Consequently, a prosecutor’s insistence that the witness not be informed of the terms of the bargain has the inevitable tendency to lead the witness to color his testimony, so as to receive the most favorable treatment from the prosecutor. No legitimate public interest is served by such a practice. Accordingly, the trial court erred when it held that any agreement not communicated to Colman was irrelevant to the issue of her credibility. The defense counsel is entitled to discover the terms of any agreement for lenient treatment negotiated on behalf of a prosecution witness. Despite the errors in this regard, however, reversal of the judgment of guilt or the special circumstance finding is not warranted. When the prosecution fails to disclose evidence favorable to the defense, “[t]he defendant must make a showing of substantial materiality and even after this showing is made reversal is not required if the prosecution establishes [that] the failure to disclose was harmless beyond a reasonable doubt.” (People v. Ruthford, supra, 14 Cal.3d at p. 409.) While the defense should have been given a fuller opportunity to discover evidence that might have permitted a stronger attack on Colman’s credibility, closing arguments on both sides demonstrate that the jury was made well aware of the possible impact of Colman’s expectation of leniency on her credibility. The prosecutor noted that “it wouldn’t make any sense if she came in here and testified unless she were hoping for consideration . . . that’s why she’s testifying.” Defense counsel emphatically brought home to the jury the potentially coercive effect of the prosecution’s tactics, declaring that “they’re holding a murder charge over her head to testify, and she’s singing like a bird, the tune that they call.” In this situation, the jury could properly assess Colman’s credibility even without testimony on a specific agreement between her attorney and the prosecution. (Cf., In re Wright (1978) 78 Cal.App.3d 788, 816 [144 Cal.Rptr. 535] [possible perjury by prosecution witness would not have had such an effect on witness’ credibility as to make a verdict of not guilty reasonably probable].) Furthermore, the evidence against defendant with respect to the charged offense was overwhelming. While Colman was an important prosecution witness, the key witness against defendant was Ronald Rose, the victim who miraculously survived despite being shot, set on fire and run over by a car. Given Rose’s testimony, and the considerable amount of corroborating evidence, the jury verdict as to guilt and the special circumstance allegation was virtually a foregone conclusion. Under the circumstances, there was no prejudice to the defendant. C. The trial court did not abuse its discretion in preventing the defense from eliciting from Colman her “professional background” as a prostitute and that her reason for flying to Fresno was to ply her trade. Prior to Colman’s testimony, the prosecution made a motion in limine to prevent the defense from eliciting from Colman on cross-examination testimony regarding alleged acts of prostitution, and to exclude certain nude photographs of Colman, apparently taken by defendant. Defendant’s counsel opposed the motion, contending that evidence of prostitution was admissible both “to show the financial situation of the parties who are cohabiting” and “to show her specific reason for going to Fresno,” and supporting admission of the photographs to show “what the relationship was” and, possibly, suggest a motive for bias. The trial court granted the motion in limine. The trial court subsequently reaffirmed both rulings when the defense claimed that the prosecution had “opened [the] door” for admission of such evidence by once characterizing Colman’s relationship with defendant as “living as man and wife,” which, defense counsel complained, “leaves the image of a rather platonic, nice situation, which is certainly a long way from the truth of what the pictures very aptly represent.” Defendant now claims that the trial court abused its discretion in limiting cross-examination of Colman with regard to her activities as a prostitute. (He does not challenge the ruling excluding the nude photographs.) Permitting the defense to elicit testimony from Colman that she engaged in acts of prostitution had an obvious potential for embarrassing or unfairly discrediting her. (Evid. Code, § 765.) The degrading impact of such questions has long been recognized. (See People v. Crandall (1899) 125 Cal. 129, 134 [57 P. 785].) The question faced by the trial court, then, in deciding on the motion in limine, was whether the patent prejudicial impact of permitting such questioning was substantially outweighed by its probative value. (Evid. Code, § 352.) In opposing the motion, the defense suggested two ways in which Colman’s testimony might be relevant. Defense counsel first suggested that it might be admissible to show the “financial situation” of Colman and defendant, but he quickly disclaimed any intention of “go[ing] into [Colman’s] life history.” Defense counsel limited himself to trying to persuade the court that he should be allowed to elicit from Colman expected testimony that her purpose in flying to Fresno on the day of the murder was “to work the streets” there in order to preclude any inference by the jury that she went to Fresno pursuant to any common scheme with defendant. The prosecutor pointed out, however, that he had already indicated in his opening statement that Colman’s presence in Fresno to meet defendant was a “pure coincidence.” (In his closing argument, the prosecutor reiterated that it was a “sheer coincidence” that Colman was there.) On this basis, the trial court concluded that, if the testimony were relevant at all, its prejudicial effect would “far outweigh” its probative value, and, accordingly, it granted the motion in limine under Evidence Code section 352. Defendant’s present claims that the trial court abused its discretion in precluding inquiry regarding Colman’s activities as a prostitute and her purpose in going to Fresno, are based on reasons other than those advanced by defense counsel at trial. He suggests that the defense should have been allowed to elicit Colman’s testimony as to why she went to Fresno in an attempt to show that she did not actually go there for purposes of prostitution—but rather, to meet defendant or, as suggested in defendant’s reply brief, to meet Richard Graybill. Defendant’s argument appears to rest on nothing more than a speculative possibility that, by vigorous cross-examination, defense counsel might have succeeded in breaking down the witness and exposing her story of going to Fresno for prostitution as a fabrication. (Cf. People v. Alfaro (1976) 61 Cal.App.3d 414 [132 Cal.Rptr. 356].) Certainly, it appears from the arguments on the motion that defense counsel had not thought of trying to break down Colman’s story (nor is it apparent from the record how he learned what her testimony would be); indeed, he seemed perfectly satisfied with that explanation and only wanted the jury to hear it too. In any event, if it was possible that Colman had another reason for going to Fresno that could have been discovered by cross-examination, defendant failed to apprise the court of this, and, in light of the obvious prejudicial effect of the expected testimony, the trial court cannot be faulted for excluding it. (People v. Burton (1961) 55 Cal.2d 328, 344-345 [11 Cal.Rptr; 65, 359 P.2d 433]; People v. Coleman (1970) 8 Cal.App.3d 722, 728-731 [87 Cal.Rptr. 554]; People v. Lancaster (1957) 148 Cal.App.2d 187, 195-196 [306 P.2d 626].) The second possible ground suggested by defendant for admitting testimony about Colman’s acts of prostitution must be rejected for the same reason. He asserts that if her activities as a prostitute were directed by defendant, acting as her “pimp,” then that might have been a motive for giving biased, untruthful testimony, since “many prostitutes have strong feelings of resentment and outrage against [their pimps].” This ground of asserted relevance rests upon a speculative generalization about the relationships between prostitutes and pimps, which the trial court might well have deemed insufficient by itself to outweigh the certain prejudice that would result from admission of the testimony. Defense counsel’s momentary flirtation with the notion that the testimony might be relevant to show the “financial situation” of Colman and defendant was surely not the same thing as suggesting that Colman had a motive for bias in her “outrage” against defendant. It is noteworthy in this regard that, though the prosecutor stressed that the People did not “seek to prohibit the defendant from any relevant testimony regarding their relationship ...” and the court stated, in essence, that its assessment of the relevancy of Colman’s activities might change depending upon defendant’s other testimony, the defense made no attempt to show by defendant’s testimony that the relationship between him and Colman before and at the time of the killing was anything but amicable. Moreover, since the ground asserted for admitting the testimony was not raised before the trial court, it may not be considered now for the first time. (People v. Coleman, supra, 8 Cal.App.3d at pp. 729-731.) D. The trial court did not err in admitting a tape recording of a telephone conversation between defendant and Richard Graybill while defendant was a fugitive. Defendant contends that the admission into evidence of a tape recording of a telephone conversation between him and Richard Graybill, while defendant was a fugitive, violated his constitutional rights to freedom from unreasonable searches, privacy, and due process. The facts were established at a hearing on defendant’s motion to suppress. (§ 1538.5.) In December 1977, Graybill learned that Colman (who had lived with Graybill until she moved in with defendant) was being sought by police. A short time later, he received a telephone call from defendant. Graybill informed the Madera County Sheriff’s office of the call, and agreed to try to lure defendant into a position where he could be captured. Defendant remained in telephone contact with Graybill, sometimes calling him at home and other times by prearrangement at various public telephones (in order to minimize the chances of the calls being traced). In January 1978, upon the advice of a detective, Graybill recorded a telephone conversation with defendant on his tape recorder. The tape (which was also Graybill’s property) was subsequently admitted (in its entirety, by stipulation) against defendant at the trial. Defendant asks us to reconsider our holding in People v. Murphy (1972) 8 Cal.3d 349 [105 Cal.Rptr. 138, 503 P.2d 594], which upheld against a Fourth Amendment challenge the admissibility of tape recordings of conversations, on the telephone and in-person, surreptitiously made by associates of the defendant who were acting at the direction of law enforcement officers. (Id., at pp. 358-361; see also United States v. White (1971) 401 U.S. 745 [28 L.Ed.2d 453, 91 S.Ct. 1122]; Hoffa v. United States (1966) 385 U.S. 293 [17 L.Ed.2d 374, 87 S.Ct. 408].) He criticizes as “unpersuasive” the rationale of cases, including Murphy, upholding the admissibility of such recordings. Murphy and the United States Supreme Court decisions upon which it relies emphasize that a defendant has no constitutionally protected expectation that his confidant will not reveal a conversation to the police, and the recording merely corroborates and assures the accuracy of the confidant’s later testimony. Defendant counters that, as a practical matter, it is the witness’s testimony which merely “supplements” the tape in most such situations. He points out that, without the tape, Graybill’s credibility might have been such that the jury would not have believed this recounting of the conversation. An apt response to this argument is contained in Justice Harlan’s opinion in Lopez v. United States (1963) 373 U.S. 427 [10 L.Ed.2d 462, 83 S.Ct. 1381]: “Stripped to its essentials, petitioner’s argument amounts to saying that he has a constitutional right to rely on possible flaws in the agent’s memory, or to challenge the agent’s credibility without being beset by corroborating evidence that is not susceptible to impeachment. For no other argument can justify excluding an accurate version of a conversation that the agent could testify to from memory. We think the risk that petitioner took in offering a bribe to [the agent] fairly included the risk that the offer would be accurately reproduced in court, whether by faultless memory or mechanical recording.” (Id., at p. 439 [10 L.Ed.2d at p. 471], fn. omitted; quoted in People v. Murphy, supra, 8 Cal.3d at p. 360.) More fundamentally, defendant objects to characterizing as merely a case of misplaced trust a situation in which an associate of the accused acts at the direction of the state. The point made in Murphy and the federal precedent is that the accused in such a case is not a passive victim of a government intrusion into his zone of privacy; rather, he has, by taking a companion into his confidence, in essence extended his zone of privacy to embrace the companion as to any confidences so disclosed. There is simply no constitutional principle that prohibits the recipient of a confidence from breaching the trust reposed in him not to disclose it to others, including the police. Murphy is in accord with settled federal statutory law (tit. HI, Omnibus Crime Control and Safe Streets Act, 18 U.S.C. § 2511 (2)(c) and (d)), as well as applicable California statutes. (§ 633.) We see no reason to reconsider it now. Finally, defendant objects to admission of the tape recording under the rationale of People v. Hitch (1974) 12 Cal.3d 641 [117 Cal.Rptr. 9, 527 P.2d 361]. The recording begins in midsentence and Graybill admitted that he did not turn the tape recorder on until perhaps 15 seconds after the conversation had begun. Defendant contends, by analogy to Hitch, that the deputy who advised Graybill to record the telephone conversation had a duty to assure that the entire conversation was recorded, so that the recording could not be used in a misleading manner. Defendant failed to make this objection in the trial court, though, so it may not now be considered by us. (People v. Welch (1972) 8 Cal.3d 106, 114-115 [104 Cal.Rptr. 217, 501 P.2d 225].) E. The trial court correctly admitted photographs of the murder victim. Defendant complains that certain photographs depicting the charred remains of the murder victim in the Ranchero were unduly gruesome and should not have been admitted in light of their limited probative value. (7a) “Admission of photos of victims lies within the discretion of the trial court unless their probative value is clearly outweighed by their prejudicial effect.” (People v. Cruz (1980) 26 Cal.3d 233, 253 [162 Cal.Rptr. 1, 605 P.2d 830].) Here the trial court clearly understood its duty to weigh the photographs’ relevance against their tendency to prejudice the jury (compare People v. Ford (1964) 60 Cal.2d 772, 801 [36 Cal.Rptr. 620, 388 P.2d 892]), and it excluded one of the four proffered photographs of the victim in the Ranchero as cumulative. (See People v. Haskett (1982) 30 Cal.3d 841, 859 [180 Cal.Rptr. 640, 640 P.2d 776]; People v. Ramos (1982) 30 Cal.3d 553, 576-577 [180 Cal.Rptr. 266, 639 P.2d 908].) We have reviewed the remaining photos and find no abuse of discretion in their admission. Defendant contends that they would have been cumulative on the issue of malice to the undisputed testimony regarding the burning of the Ranchero and the victim’s body. Even so assuming, we cannot say the trial court was wrong in apparently accepting the prosecutor’s argument that the position of the body in the vehicle might help the jury evaluate testimony that defendant extracted the victims’ wallets and searched them and a potential issue of self-defense based on the presence of Rose’s revolver in the vehicle. F. The trial court did not abuse its discretion in permitting defendant to be impeached by three prior felony convictions. Defendant contends that the trial court improperly allowed him to be impeached by the unduly cumulative admission into evidence of all three of his prior burglary convictions. The trial court properly applied the test for admission of prior convictions for impeachment outlined in People v. Beagle, supra, 6 Cal.3d at pages 451-454, and did not abuse its discretion in admitting the three essentially contemporaneous convictions. The first factor under Beagle is whether a conviction reflects adversely on the defendant’s honesty or veracity. It is settled that burglaries accomplished with larcenous intent (as reflected in defendant’s conviction records) may be used for this purpose. (People v. Bishop (1982) 132 Cal.App.3d 717, 721 [183 Cal.Rptr. 414]; People v. Keating (1981) 118 Cal.App.3d 172, 180 [173 Cal.Rptr. 286].) Further, we think the fact that defendant was convicted for burglaries in three counties more or less contemporaneously is suggestive of an ambitious premeditated dishonesty of which the court could reasonably conclude the jury ought to be aware. The other factors also point to admission. The convictions were “comparatively recent,” in 1976, while the instant offenses took place in 1977. There is no suggestion that the burglaries involved the sort of assaultive conduct that was central to the instant offenses, that is, they do not “present a close analogy to the current charges.” And, finally, defendant was not deterred from testifying, so the fourth factor identified in Beagle is inapplicable. We are not insensitive to the concern expressed by defendant that the admission of all three burglary convictions may well have depicted him to the jury as an “habitual offender.” However, defendant did not object on the ground of cumulativeness, arguing only about the dissimilarity of the prior offenses to the present offenses. (People v. Welch, supra, 8 Cal.3d at pp. 114-115.) Consequently, we are unprepared to say that the trial court abused its discretion in admitting all three prior burglary convictions, especially in view of the contemporaneity of the convictions, which might be seen as shedding light on the extent of defendant’s dishonesty. G. The trial court correctly ruled that defendant had no right to refuse to testify regarding assertedly “collateral” areas during cross-examination. Defendant testified in his own behalf. During cross-examination, the prosecutor interrogated him extensively on his alibi and on his version of the circumstances surrounding the cocaine deal in which Bartulis and Rose were alleged participants. He refused to answer a number of these questions, initially on Fifth Amendment grounds and later, after the trial court informed him that the privilege did not apply, on the ground that he would be killed if he answered. Conceding that he waived most of the protection of the privilege in taking the stand (People v. Saddler (1979) 24 Cal.3d 671, 679 [156 Cal.Rptr. 871, 597 P.2d 130]), defendant nonetheless contends that the prosecutor’s cross-examination was not properly limited to matters covered in the direct examination, but ranged far afield. Defendant refused to answer questions about the bank account into which he deposited $6,200 on the day Rose gave him $10,000 (which defendant testified he passed on to Graybill through Colman); the identities of associates with whom he met in Sacramento on the night of the murder; the source of the cocaine supply; its manner of delivery; the identity of the smuggler; the origin of the men in pinstripe suits that defendant testified provided “security” for his barbecue; whether the men carried machine guns; the identities of other attendees of the party; whether the cocaine transaction was completed; the means of delivery of the cocaine; its means of distribution; the location of the promissory note from Rose between the date of the murder and its delivery to defense counsel; and the extent of defendant’s personal knowledge of how murder “contracts” are put out. Examination of the questions which defendant refused to answer discloses that virtually all of them sought detailed information about the grandiose cocaine deal that defendant testified to on direct, with an evident and proper purpose of exposing the story as an extravagant fabrication. Other questions also came within the broad scope of permissible cross-examination. The prosecution certainly had a right to inquire about the identities of participants in the meeting in Sacramento, who were supposed witnesses to defendant’s alibi. Similarly, since there was a dispute between Rose’s and defendant’s testimony regarding the reasons for Rose’s issuance of the $25,000 promissory note, testimony concerning what happened to it while it was in defendant’s custody was relevant. Finally, the question regarding defendant’s knowledge concerning death “contracts” properly arose out of Colman’s testimony that defendant told her that if Rose lived, “he would have to try to get a contract on him.” “Although the permissible scope of cross-examination in California is restricted to the scope of the direct examination (Evid. Code, §§ 772, subd. (d), 761; Witkin, Cal. Evidence (2d ed. 1966) § 1204), when a defendant ‘takes the stand and makes a general denial of the crime with which he is charged the permissible scope of cross-examination is very wide.’ [Citations.]” (pPeople v. Saddler, supra, 24 Cal.3d at p. 679.) H. The erroneous instruction on the special circumstance of murder in the commission of a robbery was harmless. Defendant contends that the trial court gave the jury an erroneous instruction on the special circumstance of murder in the commission of a robbery (former § 190.2, subd. (c)(3)(i)), which failed to apprise the jury of all the facts that must be proved to establish the existence of the special circumstance. At the time of the killing, on December 7, 1977, section 190.2 provided: “The penalty for a defendant found guilty of murder in the first degree shall be death or confinement in the state prison for life without possibility of parole in any case in which one or more of the following special circumstances has been charged and specially found ... to be true . ... [11] (c) The defendant was [i] personally present during the commission of the act or acts causing death, and [2] with intent to cause death [3] physically aided or committed such act or acts causing death and any of the following additional circumstances exists: ... [1] (3) [4] The murder was willful, deliberate, and premeditated and [5] was committed during the commission or attempted commission of any of the following crimes: [f] (i) Robbery in violation of Section 211. . . .” (Italics and bracketed numerals added.) Rather than giving the 1977 revision of the CALJIC instruction on the special circumstance of murder in the commission of a robbery, the trial court gave the jury a modified version of the 1979 CALJIC instruction, which, reflecting the changes in section 190.2 wrought by the 1978 death penalty initiative, deleted most of the required findings. The trial court instructed the jury, in pertinent part: “If you find the Defendant in this case guilty of murder of the first degree, you must then determine if the murder was committed under the following special circumstance: the murder was willful, deliberate and premeditated, and was committed during the commission or attempted commission of robbery in violation of Section 211, Penal Code, [ft A special circumstance must be proved beyond a reasonable doubt, [t] If you have a reasonable doubt as to whether a special circumstance is true, it is your duty to find that it is not true. [|] In order to find the special circumstance charged in this case to be true or untrue, you must agree unanimously, [f] You will include in your verdict on a form which will be supplied whether the special circumstance is or is not true. [!] To find that the special circumstance referred to in these instructions as murder in the commission of robbery, it must be proved: That the murder was committed while the Defendant was engaged in the commission or attempted commission of a robbery.” Although we agree with defendant that he was entitled to instructions on the special circumstance of murder in the commission of a robbery that apprised the jury of all of the findings required by section 190.2 as it read at the time of the offense, we conclude that the trial court’s error was harmless since the jury necessarily made these findings implicitly in reaching the verdict that it did. (See People v. Sedeno (1974) 10 Cal.3d 703, 721 [112 Cal.Rptr. 1, 518 P.2d 913]; People v. Tanner (1979) 95 Cal.App.3d 948, 956-957 [157 P.2d 465] [erroneous instruction that intent did not matter for crime of arson was harmless since first degree murder verdicts showed finding of specific intent].) The trial court instructed the jury that the special circumstance which it was supposed to find true or untrue was that “[t]he murder was willful, deliberate and premeditated and was committed during the commission or attempted commission of robbery. ...” (Italics added.) Defendant urges, however, that the subsequent instruction—“[t]o find the special circumstance ... it must be proved: that the murder was committed while the Defendant was engaged in the commission or attempted commission of a robbery”—might have suggested to the jury that is all that must be proved, resulting in a perceived conflict in the instructions. No real occasion for confusion existed, though. The latter instruction does not say that only the fact that the murder was committed in the commission of a robbery must be proved; it merely reiterates the need for a finding that the murder was so committed. In finding that the special circumstance allegation was true, the jury specifically found “that the murder of Bruce P. Bartulis was willfull [sic], deliberate and premeditated, and was personally committed by [defendant] during the commission or attempted commission of the crime of robbery. ...” Moreover, the prosecutor in his. closing argument accurately informed the jury in this regard: “You’ll have to determine whether the special circumstance is true or not. The special circumstance alleged is that the murder was willful, deliberate and premeditated, and it was committed during the commission or attempted commission of a robbery, [f] Now, in order, of course, to find that special circumstance, you have to find what is called premeditation. . . .” It is ordinarily presumed that jurors are intelligent persons capable of understanding and correlating all jury instructions that are given. (People v. Coleman (1979) 89 Cal.App.3d 312, 323 [152 Cal.Rptr. 407]; People v. Romo (1975) 47 Cal.App.3d 976, 990 [121 Cal.Rptr. 684].) Defendant is correct, though, when he complains that the jury was not apprised by the instructions that the special circumstance of murder in the commission of a robbery also required proof that (1) he was “personally present” when the murder was committed, (2) he “physically aided or committed” the killing, and (3) he did so “with intent to cause death.” Nevertheless, this error was harmless because the jury necessarily resolved each of the foregoing issues adversely to defendant. As previously noted, the jury’s special finding expressly states that the murder “was personally committed by [defendant] . . .,” and the jury also found to be true the allegation that defendant “personally use[d] a firearm” in the commission of the murder. These findings necessarily reflect the jury’s conclusions that defendant was personally present during the commission of the murder and that he “physically aided or committed” the killing. Despite the lack of a proper instruction, the jury’s explicit findings that defendant “personally committed” the murder, and used a firearm in doing so, render fantastic, not merely “improbable,” defendant’s speculation that the jury might have believed that Colman did the shooting and defendant was merely a passive accomplice who armed himself later during the asportation of the victims’ wallets. Finally, though the first degree murder verdict does not by itself show that the jury determined that defendant intended to cause Bartulis’s death, since it may have been based on a felony-murder theory, the special finding that the murder was willful, deliberate and premeditated does. Those terms were defined in the instructions on first degree murder: “The word ‘willful,’ as used in this instruction, means intentional, [f] The word ‘deliberate’ means formed or arrived at or determined upon as a result of careful thought and weighing of considerations for and against the proposed course of action. The word ‘premeditated’ means considered beforehand, [t] If you find that the killing was preceded and accompanied by a clear, deliberate intent on the part of the defendant to kill, which was the result of deliberation and premeditation, so that it must have been formed upon pre-existing reflection and not under a sudden heat of passion or other condition precluding the idea of deliberation, it is murder of the first degree, [f] The law does not undertake to measure in units of time the length of the period during which the thought must be pondered before it can ripen into an intent to kill which is truly deliberate and premeditated. The time will vary with different individuals and under varying circumstances, [f] The true test is not the duration of time, but rather the extent of the reflection. A cold, calculated judgment and decision may be arrived at in a short period of time, but a mere unconsidered and rash impulse, even though it includes an intent to kill, is not such deliberation and premeditation as will fix an unlawful killing as murder of the first degree, [f] To constitute a deliberate and premeditated killing, the slayer must weigh and consider the question of killing and the reasons for and against such a choice and, having in mind the consequences, he decides to and does kill.” (Italics added.) Thus, to commit a “willful” murder, the actor must possess an intent to kill. (People v. Gorshen (1959) 51 Cal.2d 716, 730 [336 P.2d 492].) It has been held that a determination that a killing was deliberate and premeditated is not the equivalent of a finding of malice. (Id., at pp. 731-733; People v. Horn (1974) 12 Cal.3d 290, 298 [115 Cal.Rptr. 516, 524 P.2d 1300]; People v. Sedeno, supra, 10 Cal.3d at p. 722.) Here, though, we are concerned only with intent to kill. That a jury verdict of willful, deliberate and premeditated murder necessarily embraces such a finding was recognized in People v. Sedeno, supra, “In Sedeno, the trial court erred in failing to give an instruction sua sponte on involuntary manslaughter due to diminished capacity. (10 Cal.3d at p. 720.) Such an instruction would have required the jury to specifically determine whether the accused had acted without an intent to kill and malice. The error was harmless as to the question of the intent to kill because the jury had received instructions on second degree murder without an intent to kill and had specifically and necessarily rejected that theory by returning a verdict of first degree murder. (Id., at p. 721.)” (People v. Wickersham (1982) 32 Cal.3d 307, 335-336 [185 Cal.Rptr. 436, 650 P.2d 311], italics added.) I. The trial court was not required to instruct the jury sua sponte concerning the “incidental robbery” theory. Defendant argues that the special circumstance finding must be reversed because the trial court failed to instruct the jury sua sponte that the special circumstance of murder “in the commission of a robbery” does not apply to a murder accompanied by an “incidental” robbery, as was held in People v. Green (1980) 27 Cal.3d 1, 61-62 [164 Cal.Rptr. 1, 609 P.2d 468]. It was not conceivable in this case that the jury might have found evidence to support a finding that the victims’ wallets were taken only to hide their identities. On the facts presented here, Green’s “incidental robbery” doctrine cannot properly be characterized as a general principle of law “closely and openly connected with the facts before the court” from which a sua sponte duty to instruct could arise. (See People v. Robertson (1982) 33 Cal.3d 21, 52 [188 Cal.Rptr. 77, 655 P.2d 279]; People v. St. Martin (1970) 1 Cal.3d 524, 531 [83 Cal.Rptr. 166, 463 P.2d 390]; People v. Sedeno, supra, 10 Cal.3d at p. 720.) J. Defendant was not deprived of the effective assistance of counsel at the guilt phase. Defendant raises several unrelated contentions concerning claimed ineffectiveness of his trial counsel during the guilt phase of his trial. To establish constitutionally inadequate representation, defendant must show that defense counsel failed to act in a manner to be expected of reasonably competent attorneys acting as diligent advocates, and that (1) counsel’s acts or omissions resulted in the withdrawal of a potentially meritorious defense, or (2) it is reasonably probable that a determination more favorable to defendant would have resulted in the absence of counsel’s failings. (People v. Pope (1979) 23 Cal.3d 412, 425 [152 Cal.Rptr. 732, 590 P.2d 859, 2 A.L.R.4th 1]; People v. Fosselman (1983) 33 Cal.3d 572, 584 [189 Cal.Rptr. 855, 659 P.2d 1144].) He has not succeeded in doing so. We have already concluded that the error in instructing the jury on the special circumstance of murder in the commission of a robbery was harmless. Consequently, defense counsel’s failure to bring the correct instruction to the attention of the court did not withdraw a potentially meritorious defense. Anticipating a holding that his failure to move to set aside the information under section 995 barred his claim of ineffective assistance of counsel at the preliminary hearing (as indeed we have concluded, ante), defendant contends that reasonably competent counsel would have made such a motion. The record shows that defendant, with knowledge of the conflict, chose to be represented at the preliminary hearing by the public defender, and sought other co
