Opinion PANELLI, J. This is an automatic appeal from a judgment of death imposed under the 1978 law. (Pen. Code, § 190.1 et seq.; see id., § 1239, subd. (b).) Defendant was convicted of kidnapping for the purpose of robbery (§ 209), robbery (§211) and first degree murder (§§ 187, 189). The jury found true the firearm-use allegations (§ 12022.5) and the special circumstance allegations that the murder had been committed during a robbery and a kidnapping (§ 190.2, subd. (a)(17)(i), (ii)). In a separate proceeding the jury also found true the special circumstance allegation that defendant had previously been convicted of a first degree murder. (§ 190.2, subd. (a)(2).) The jury fixed punishment at death. The court ordered the prison terms imposed on the kidnapping for robbery and robbery charges stayed pending imposition of the death penalty. We affirm the judgment in its entirety. Facts I. Guilt Phase Myrtle Benham was beaten to death in an abandoned shack in the desert near Daggett, California, on March 20, 1981. The San Bernardino Sheriff’s Department found her body one week later. She was lying face down and nude below the waist. Some of her clothing was around her left foot. In a seemingly unrelated incident, defendant and Michael Crenshaw were arrested on March 24, 1981, in San Jose. Two San Jose police officers observed Crenshaw and defendant sleeping in a car while the engine was running. When the officers approached the car and asked defendant, the driver, to get out, defendant drove away, knocking one officer to the ground. Defendant and Crenshaw were arrested after a high speed chase that culminated in their car colliding with a police car. During the chase a .25-caliber Raven automatic pistol was thrown from the car. A .25-caliber Galesi pistol was found under the driver’s seat. Credit cards in the names of Minnie Ola White and Jim Rankin were found in the car, as were two tape recorders belonging to Jim Rankin. When defendant was booked, he had in his possession rings belonging to Benham and White. Prosecution Evidence. Crenshaw testified at the preliminary hearing, but at trial asserted his Fifth Amendment privilege and refused to testify. The court determined Crenshaw was unavailable as a witness and allowed his preliminary hearing testimony to be read to the jury. Crenshaw testified he and defendant were driving from Las Vegas on March 20, 1981, when they stopped in Baker at an Exxon gas station where Benham worked. Defendant emerged from the car with a pistol in each hand, took the money and cash drawer from the register and ordered Benham into the car trunk. Defendant eventually stopped the car near a shack in the desert and told Crenshaw he was going to “take the lady inside” and have sex with her. When Crenshaw later went inside the shack, he saw defendant, his pants down, lying on top of Benham. Benham was face down, nude below the waist. Defendant hit her in the head with a pipe, then left the area with Crenshaw. After driving to Barstow, the two burned the car. Much of Crenshaw’s testimony was corroborated by Charles Laughlin, who claimed to have spoken with defendant on several occasions while the two were in jail. Evidence was admitted showing defendant had been convicted of the first degree murder of White. On March 21, 1981, the day after the Benham murder, White’s body was found 14 miles north of Blythe (near Vidal Junction, California) in the trunk of her car. She had been killed by a bullet from the Raven automatic pistol thrown from the car during the March 24 chase in San Jose. A piece of skin tissue consistent with White’s blood type was found on defendant’s trousers when he was arrested. Laughlin testified defendant told him that while driving to California he and Crenshaw had noticed an apparently abandoned car. When they approached the car they found an elderly woman in the front seat. They forced her into the trunk, shot her and took her money and valuables. At the time defendant and Crenshaw kidnapped Benham, they were driving a car belonging to Rankin. Rankin was last seen at a Kansas City restaurant on March 18, 1981. Laughlin testified defendant told him about kidnapping a man in Kansas City, putting the man in the trunk of his own car, taking his money and jewelry and then driving off to California. Leroy Combs testified that when he saw defendant on March 11, 1981, he was alone and in possession of two firearms—the Raven and Galesi pistols. Defense Evidence. The defense introduced evidence of a polygraph test indicating defendant did not himself kill Benham, but he had been present. Evidence was also presented that Crenshaw had pleaded guilty to the first degree murder of White. Defendant testified in his own behalf. He admitted he had escaped from Monterey County jail and on March 11, 1981, had kidnapped Combs. Defendant forced Combs to drive to Los Angeles and later placed him in the trunk of the car. After the Combs kidnapping he took a Greyhound bus to St. Louis, Missouri to meet Crenshaw, who lived in nearby Berkeley. He hitchhiked from the Greyhound station to Crenshaw’s house. His plan was to have the two work their way back to California through various robberies and thefts. Although both pistols belonged to him, he carried the Galesi and gave Crenshaw the Raven. He and Crenshaw stole Rankin’s car from a Kansas City restaurant for transportation to California. The theft was defendant’s idea. Rankin had left the keys in the car and gone off with a woman in another car. En route to California they drove through Las Vegas to snatch a purse for money; defendant snatched the purse. Crenshaw and he robbed the Exxon station together. Defendant was the first to pull his weapon and demand money. Afterward, Crenshaw and Benham got into the backseat of the car. Benham was never in the trunk. Defendant drove to the deserted shack to let Benham go. Crenshaw took her into the shack to tie her up and leave her. When Crenshaw returned a few minutes later, he made no mention of raping or killing Benham. Defendant and Crenshaw then drove to Barstow, where defendant stole another car and the two burned Rankin’s car. With defendant using Rankin’s credit card in Vidal Junction to pay for gas, the two returned to Las Vegas before turning back towards Los Angeles. While Crenshaw drove, defendant fell asleep. He later awoke near Blythe to find Crenshaw gone and the car parked on a side road. Defendant did not know that White had been killed in the area. Defendant denied Laughlin’s testimony and claimed all of Laughlin’s information resulted from his having gone through defendant’s papers and police reports while the two were in jail together. II. Penalty Phase Evidence Prosecution Evidence. At the penalty phase the prosecution introduced evidence that on March 10, 1981, defendant and one Olden robbed a service station in Arroyo Grande, California. Michael Buss, the attendant, testified Olden wielded a shotgun while defendant ripped out the telephone and took the keys to Buss’s fiancee’s car. On March 17, 1981, William Parr, a St. Louis, Missouri cab driver, was dispatched to a building near the Greyhound depot. His body was found in a park several hours later, a bullet through his brain. The bullet came from defendant’s Galesi firearm. Parr’s taxicab was found abandoned near Crenshaw’s residence. Thomas Smith, an inmate at Chino State prison, testified that on his arrival at the prison defendant advised him how to protect himself from other inmates and offered him a weapon. Defendant subsequently told Smith he was part of a group that would protect him if Smith would allow its members to sodomize him. Defendant told Smith he had “no choice.” Thereafter defendant held Smith’s head while another man sodomized him. Members of the group subsequently kicked and choked Smith; he did not know if defendant participated in the beating. Inmate Laughlin testified to Rankin’s death. Defendant told Laughlin he placed Rankin in the trunk of Rankin’s vehicle, then later let him out and made him plead for his life before shooting him. Defendant partially covered Rankin’s body with dirt and a vinyl tarp. Defendant told Laughlin that Rankin “was made to beg for his life and he filled his head with lead.” Defense Evidence. Defendant presented evidence Smith had given inconsistent statements concerning defendant’s part in the sodomy attack on him. Defendant also presented evidence he was not involved in the attack. Terry Caylor, an incarcerated felon, testified Laughlin said he would not have to stand trial in his own case because he was going to testify against defendant. Laughlin told Caylor he and Crenshaw had a “deal” and he could get all the information he needed from Crenshaw. Caylor saw Laughlin and Crenshaw talking together. The parties stipulated that the escape charge pending against Laughlin had been reviewed and dismissed by a prison review board for insufficient evidence and no further action was taken on the charge. The testimony of George Gunn, a Missouri state court justice, at defendant’s Riverside trial for the murder of White was presented. Defendant and a companion robbed Gunn in Missouri in 1979. Defendant’s companion held a revolver to Gunn’s face with the hammer cocked. After the two took Gunn’s money, defendant returned Gunn’s glasses before fleeing. Defendant’s family members and numerous teachers and counselors testified to his background and difficult childhood. Defendant was the product of an interracial marriage, which subjected him to racial epithets and left him confused about his identity. His father’s military career led to an unstable family life, with his father, a harsh authoritarian, frequently absent for long periods of time. Defendant had significant learning and social problems in school, but the schools lacked the resources to give him the help he needed. Expert testimony indicated defendant had some brain damage that affected his behavior and personality. He was a hyperkinetic child and continues to suffer from an attention deficit disorder, but he could function in the structured prison environment. Defendant tends to be a follower, not a leader. Defendant was close and affectionate with his family. He has fathered two children; he married the mother of one. Discussion I. Guilt Phase Issues A. Denial of Representative and Impartial Jury. Defendant contends the exclusion of some potential jurors for cause in accord with Witherspoon v. Illinois (1968) 391 U.S. 510 [20 L.Ed.2d 776, 88 S.Ct. 1770] denied him his due process and Sixth Amendment rights to an impartial and representative jury. The United States Supreme Court has rejected these contentions (Lockhart v. McCree (1986) 476 U.S. 162 [90 L.Ed.2d 137, 106 S.Ct. 1758]), as have we (e.g., People v. Babbitt (1988) 45 Cal.3d 660, 679 [248 Cal.Rptr. 69, 755 P.2d 253]; People v. Anderson (1985) 38 Cal.3d 58, 60 [210 Cal.Rptr. 777, 694 P.2d 1149]). B. Disclosing Prior-murder-conviction Special Circumstance. Defendant offered to stipulate to the prior-murder conviction underlying the prior-murder-conviction special-circumstance allegation (§ 190.2, subd. (a)(2)) to keep it from the jury before trial. The court rejected the stipulation on grounds it was precluded by article I, section 28, subdivision (f) of the California Constitution (Proposition 8), which provides that “[w]hen a prior felony conviction is an element of any felony offense, it shall be proven to the trier of fact in open court.” As the Attorney General concedes, however, because the charged murder in this case occurred before June 9, 1982, Proposition 8 has no application. (People v. Smith (1983) 34 Cal.3d 251 [193 Cal.Rptr. 692, 667 P.2d 149].) Defendant asserts the court erred in rejecting the stipulation. Citing section 1093, section 190.1, People v. Hall (1980) 28 Cal.3d 143 [167 Cal.Rptr. 844, 616 P.2d 826] and People v. Bracamonte (1981) 119 Cal.App.3d 644 [174 Cal.Rptr. 191], he argues he had both a statutory and constitutional due process right to a bifurcated trial on the truth of the prior-murder-conviction special-circumstance allegation. Assuming, without deciding, that the court erred in refusing defendant’s stipulation, the error was harmless in light of our determination, post at pages 20-22 that evidence of the prior murder was properly admitted at trial. Moreover, in light of the overwhelming evidence of defendant’s guilt of the Benham murder, it is not reasonably probable a result more favorable to defendant would have been reached had the jury not been informed of the prior-murder conviction. (People v. Watson (1956) 46 Cal.2d 818, 836 [299 P.2d 243].) C. Admission of Uncharged Crimes. Defendant asserts error in the admission of evidence of the Riverside murder of White, the robbery and kidnapping of Rankin and the kidnapping of Combs. The principles governing admission of uncharged crimes are well established. “Evidence of other crimes or prior bad acts is inadmissible solely to prove an accused had the predisposition to commit the charged offense. (Evid. Code, § 1101, subd. (a); People v. Alcala (1984) 36 Cal.3d 604, 631 [205 Cal.Rptr. 775, 685 P.2d 1126]; People v. Willoughby (1985) 164 Cal.App.3d 1054, 1062 [210 Cal.Rptr. 880].) However, the evidence may be admitted when it is relevant to prove another issue in the case such as opportunity, intent, knowledge, identity, or absence of mistake. (Evid. Code, § 1101, subd. (b).) Because of its inflammatory impact, evidence relevant on one of these theories should be excluded when it is ‘not relevant to an issue expressly in dispute [citation], . . . “merely cumulative . . .” [citations], or . . . more prejudicial than probative under all the circumstances. [Citations.]’ (People v. Alcala, supra, at pp. 631-632. Accord, People v. Thompson (1980) 27 Cal.3d 303, 314-318 [165 Cal.Rptr. 289, 611 P.2d 883].)” (People v. Miranda (1987) 44 Cal.3d 57, 82-83 [241 Cal.Rptr. 594, 744 P.2d 1127].) In sum, to be admissible, evidence of other crimes must be relevant to some material fact in issue, must have a tendency to prove that fact, and must not contravene other policies limiting admission, such as Evidence Code section 352. (People v. Thompson (1988) 45 Cal.3d 86, 109 [246 Cal.Rptr. 245, 753 P.2d 37]; People v. Thompson (1980) 27 Cal.3d 303, 315-318 [165 Cal.Rptr. 289, 611 P.2d 883].) 1. The Rankin Offenses. Defendant acknowledges evidence concerning the Kansas City theft of Rankin’s car and credit cards was admissible as intertwined with the charged crimes, in that Rankin’s car was used to transport Benham to the scene of her murder and defendant used his credit cards to buy gas in Vidal Junction. (E.g., People v. Viniegra (1982) 130 Cal.App.3d 577, 582 [181 Cal.Rptr. 848].) Defendant argues the court erred in failing to sever from the admissible evidence the further evidence of Rankin’s kidnapping and murder—his murder implied from evidence he was never seen again after defendant stole his car. (People v. Dabb (1948) 32 Cal.2d 491, 500 [197 P.2d 1]; People v. Haston (1968) 69 Cal.2d 233, 245 [70 Cal.Rptr. 419, 444 P.2d 91].) Before allowing Laughlin to testify to defendant’s jailhouse statements, the trial court ruled admissible evidence concerning the circumstances of the taking of Rankin’s car, including when he was last seen, but ruled inadmissible evidence Rankin is missing or was murdered. Contrary to defendant’s assertion the court did not weigh the evidence’s prejudicial effect against its probative value (Evid. Code, § 352), the court expressly recognized the “serious consequences” of admitting evidence of the Rankin offenses. Thereafter, asked by the prosecutor what defendant had told him about the circumstances surrounding the theft of a car, Laughlin replied defendant said he had stolen a vehicle from a male in the parking lot of a restaurant in Kansas City, had taken money and jewelry from him, and had then placed him in the trunk of the car and left. Defense counsel did not object. Rankin’s wife testified the blue Buick used in the crime resembled her husband’s and identified the stolen credit cards as his. He normally kept the cards in his wallet, which he kept in his pants pocket. He was due back from Kansas City March 20, 1981, but she has not seen him since. We believe in its ruling the trial court properly severed the most prejudicial aspects of the Rankin incident from the most relevant portions. (See People v. Dabb, supra, 32 Cal.2d at p. 500.) Admission of the kidnapping evidence was not error. That defendant had kidnapped Rankin was part of the circumstances of the theft of his car and credit cards and as such was relevant. Although Mrs. Rankin’s testimony she had not seen her husband since March 1981 arguably suggested Rankin was missing, the testimony was not in violation of the court’s ruling, nor did defense counsel object. The evidence, in any event, fell far short of establishing Rankin was dead or had been murdered, nor did the prosecutor exploit the issue. Any error therefore was harmless. Defendant contends it was prejudicial for the prosecutor to put Rankin’s wife on the stand—“to parade family members of murder victims before the jury.” Mrs. Rankin’s testimony concerning the Buick and the credit cards, however, was relevant and she clearly was the logical witness to establish these facts. 2. The Combs Kidnapping. On March 11, 1981, Combs was kidnapped by defendant at gunpoint and forced to drive from Santa Maria to Los Angeles, where defendant placed him in the trunk of his car, but subsequently let him go. The trial court ruled Combs could testify to defendant’s possession of both revolvers (the Raven and the Galesi), but evidence of the kidnapping should be excluded. The evidence came in, however, during cross-examination of defendant, after he denied on direct having been convicted of any serious crimes of violence. Defendant acknowledges defense counsel’s question about his convictions opened the door for the prosecutor to cross-examine defendant on the kidnapping, notwithstanding lack of a conviction for the offense. (See People v. Lanphear (1980) 26 Cal.3d 814, 833-834 [163 Cal.Rptr. 601, 608 P.2d 689], vacated California v. Lanphear (1980) 449 U.S. 810 [66 L.Ed.2d 13, 101 S.Ct. 57], reiterated People v. Lanphear (1980) 28 Cal.3d 463 [171 Cal.Rptr. 505, 622 P.2d 950].) He claims, however, counsel was incompetent for creating the situation that permitted the prosecutor to elicit evidence of the other crime. The record shows that in asking defendant about his criminal history, defense counsel misspoke. Although counsel asked defendant, “Have you ever been convicted of any serious crimes of violence such as rape or mayhem or murder or anything like that?” he intended to ask only whether or not defendant “had ever killed anybody or raped or committed murder”; indeed, until the court corrected him, this is the question counsel believed he had asked. Such a slip of the tongue does not, in our view, establish ineffective assistance of counsel. The issue, in any event, is whether counsel’s error prejudiced defendant. (People v. Fosselman (1983) 33 Cal.3d 572, 584 [189 Cal.Rptr. 855, 659 P.2d 1144]; People v. Pope (1979) 23 Cal.3d 412, 415 [152 Cal.Rptr. 732, 590 P.2d 859, 2 A.L.R.4th 1].) Although the Combs kidnapping tended to suggest defendant played a dominant role in the Benham kidnapping, in that both victims were placed in the trunk of a car, it also strongly reinforced defendant’s defense that, on his own, he did not commit homicides. At defense counsel’s request the jury heard Combs’s prior testimony at defendant’s Riverside trial, wherein Combs related how defendant, on placing him in the trunk, asked if he could breathe and later, during a stop for gasoline, asked if he was “okay” and ultimately released him unharmed. In light of all the other evidence connecting defendant to the Benham crime, including his admission of robbing Benham at the gas station and driving the car to the murder site, his possession of her rings, and Laughlin’s testimony to his confession, it is not reasonably probable a determination more favorable to defendant would have resulted in the absence of counsel’s improvident question. (People v. Pope, supra, 23 Cal.3d at p. 425; People v. Fosselman, supra, 33 Cal.3d at p. 584; see Strickland v. Washington (1984) 466 U.S. 668, 693-694 [80 L.Ed.2d 674, 697, 104 S.Ct. 2052].) 3. The White Murder. White’s body was found one day after and in the same general desert area as Benham’s abduction. Defendant asserts admission of White’s murder was error. We disagree. The evidence, rather, was admissible on the issues of intent and identity. One theory of the prosecution’s case was that defendant personally, wilfully and with premeditation and deliberation, killed Benham. Proof of this theory required that defendant be identified as the actual killer and his intent be proved. Another theory was that defendant aided and abetted Crenshaw in the killing. This theory, too, required proof of defendant’s knowledge and intent. Hence, identity and intent were material issues of importance (see, e.g., People v. Bigelow (1984) 37 Cal.3d 731, 748-749 [209 Cal.Rptr. 328, 691 P.2d 994, 64 A.L.R.4th 723]), relating to facts actually in dispute (see People v. Thompson, supra, 27 Cal.3d at p. 315). (Cf. People v. Allen (1986) 42 Cal.3d 1222, 1270-1271 [232 Cal.Rptr. 849, 729 P.2d 115] [details of former crimes admissible to show identity and intent].) Defendant cites People v. Bigelow, supra, 37 Cal.3d 731 for the proposition that even if intent were an issue, the White murder was not probative of his intent and hence was irrelevant. In Bigelow the defendant was convicted of first degree murder with felony-murder special circumstances for a murder committed with an accomplice. Evidence of defendant’s two prior robberies with the accomplice, in which defendant wielded the weapon, was admitted at the guilt phase. On appeal the Attorney General argued the two uncharged offenses were admissible to prove defendant’s identity as the triggerman in the charged offenses. We concluded otherwise. The only common marks, we observed, were defendant’s presence and that the victim was ordered to lie down. The first, we stated, was immaterial, since the defendant’s presence is not part of any modus operandi, and the second was not sufficiently distinctive to justify admissibility. {Id. at p. 749.) Here, too, defendant argues, the offenses were too dissimilar to raise an inference of identity or intent: Benham was kidnapped, White was not; Benham was beaten to death, White was shot; there was evidence of a sexual assault in connection with Benham’s death, there was none as to White. The record shows, however, substantial and distinctive similarities between the offenses. Elderly women, alone and vulnerable, were the victims in each. Their murders occurred in isolated desert areas. Items of personal property, including jewelry, were taken in both and were subsequently found in defendant’s possession. A weapon belonging to defendant was used in the White murder and the Benham robbery. In each the victim at some point was placed in the trunk of a car. In each, significantly, the victim was considerably heavier than Crenshaw, who weighed only about 120 pounds and was several inches shorter than defendant—White weighed 180 pounds and Benham was a notably “large” woman. Arson to destroy evidence was involved in both, as defendant burned the Buick used to transport Benham and burned White’s purse. On these facts, the White offense shared sufficient distinctive common marks with the Benham offense to raise an inference of identity, knowledge and intent. (See People v. Robbins (1988) 45 Cal.3d 867, 879-880 [248 Cal.Rptr. 172, 755 P.2d 355]; People v. Thornton (1974) 11 Cal.3d 738, 756 [114 Cal.Rptr. 467, 523 P.2d 267], disapproved on other grounds in People v. Flannel (1979) 25 Cal.3d 668, 684, fn. 12 [160 Cal.Rptr. 84, 603 P.2d 1].) Defendant argues that even if the White murder was relevant, the court abused its discretion in failing to weigh prejudice against probative value. (Evid. Code, § 352; People v. Green (1980) 27 Cal.3d 1, 25-26 [164 Cal.Rptr. 1, 609 P.2d 468].) Although the court did not expressly weigh the prejudicial effect of the White murder against its probative value, the record is clear the court understood its duty to make such a determination and impliedly did so. Defense counsel argued Evidence Code section 352 to the court; preliminary to its ruling the court observed that “This is probably the area where the Court can come the closest to committing some kind of error because it’s the area that provides for the greatest leeway of interpretation, I suppose, as to what the law is. [fl] The words are simple, but when you begin to apply those words, it becomes very complex;” and immediately after its ruling admitting the White evidence, the court, in ruling on the Rankin offenses, expressly referred to the prejudicial effect of the evidence under section 352. After trial, in ruling on defendant’s new trial motion, the court again recognized “the fine line in this area of uncharged offenses” and stated that from its research at the time of its rulings it was convinced the material admitted was of evidentiary value although “highly prejudicial to the defendant.” The foregoing suffices to satisfy the requirement that the record “affirmatively show that the trial judge did in fact weigh prejudice against probative value” (People v. Green, supra, 27 Cal.3d at p. 25) so as to permit meaningful appellate review and ensure that the ruling on the motion is “ ‘the product of a mature and careful reflection on the part of the judge,’ . . .” (Ibid.) Any error, therefore, in the court’s failure expressly to state on the record its determination that the probative value of the evidence outweighed its prejudicial value, on this record is nonprejudicial. (People v. Frank (1985) 38 Cal.3d 711, 731-732 [214 Cal.Rptr. 801, 700 P.2d 415].) 4. Standard of Prejudice. Relying on People v. Castro (1985) 38 Cal.3d 301 [211 Cal.Rptr. 719, 696 P.2d 111], defendant maintains that as with error in admitting priors for impeachment purposes, error in admitting other-crimes evidence for the purpose for which it was admitted is a denial of due process and thus subject to a Chapman standard of review. (Chapman v. California (1967) 386 U.S. 18 [17 L.Ed.2d 705, 87 S.Ct. 824, 24 A.L.R.3d 1065].) The Attorney General responds that Watson applies. (People v. Watson, supra, 46 Cal.2d 818.) We agree. (See People v. Rivera (1985) 41 Cal.3d 388, 393 [221 Cal.Rptr. 562, 710 P.2d 362]; People v. Tassell (1984) 36 Cal.3d 77, 89 [201 Cal.Rptr. 567, 679 P.2d 1].) Moreover, as indicated, we believe there was no error in admitting the Rankin evidence. We are of like mind concerning the White evidence. However, assuming arguendo error in admitting the White murder, it was nonprejudicial under Watson. Defendant admitted he robbed Benham and transported her to the site of her death. His lie detector test indicated he was present when she was killed. Crenshaw testified defendant robbed, kidnapped and murdered Benham. Laughlin testified defendant admitted the crimes. Defendant was in possession of the victim’s rings when he was arrested. In light of the overwhelming evidence of defendant’s participation in the charged offenses, there is no reasonable probability the result would have been more favorable to defendant had the White murder been excluded. D. Admission of Preliminary Hearing Testimony. Although Crenshaw waived his Fifth Amendment privilege against self-incrimination for purposes of the preliminary hearing, he subsequently reconsidered his position and declined to testify at trial. Over defendant’s objection, the trial court found Crenshaw to be unavailable as a witness (Evid. Code, §§ 240, 1291, subd. (a)) and permitted his preliminary hearing testimony to be read to the jury. Defendant acknowledges Crenshaw’s waiver of his Fifth Amendment privilege at the preliminary hearing did not preclude him from asserting the privilege at trial, (Overend v. Superior Court (1900) 131 Cal. 280, 284 [63 P. 372]; see People v. Maxwell (1979) 94 Cal.App.3d 562, 570 [156 Cal.Rptr. 630].) He contends, however, the use in a capital case of the transcript of accomplice testimony—testimony recognized to be “inherently untrustworthy” (see In re Miguel L. (1982) 32 Cal.3d 100, 108 [185 Cal.Rptr. 120, 649 P.2d 703])—denied him his state and federal constitutional rights to confrontation and due process (U.S. Const., 6th" and 14th Amends.; Cal. Const., art. I, § 15; § 686). Neither this court nor the United States Supreme Court has ever held the normal rules of evidence do not apply in the guilt phase of a capital case. (Cf. Lockett v. Ohio (1978) 438 U.S. 586, 604, fn. 12 [57 L.Ed.2d 973, 990, 98 S.Ct. 2954] [exclusion of irrelevant evidence at penalty phase].) Pursuant to Evidence Code section 240, a declarant who is “[e]xempted ... on the ground of privilege from testifying” is “ ‘unavailable as a witness.’ ” Evidence Code section 1291, subdivision (a)(2) provides that evidence of the former testimony of an unavailable witness is not made inadmissible by the hearsay rule if “[t]he party against whom the former testimony is offered was a party to the . . . proceeding in which the testimony was given and had the right and opportunity to cross-examine the declarant with an interest and motive similar to that which he has at the hearing.” In the instant case, Crenshaw, having invoked his privilege against self-incrimination, was unavailable as a witness. Defendant at the preliminary hearing had a full opportunity to cross-examine him and did so. (People v. Maxwell, supra, 94 Cal.App.3d at p. 571; see People v. Salas (1976) 58 Cal.App.3d 460, 468 [129 Cal.Rptr. 871].) Consequently, the statutory prerequisites to use of Crenshaw’s preliminary hearing testimony were satisfied. It is settled that where, as here, the witness is unavailable and the defendant at the preliminary hearing had the opportunity and similar interest and motive as at trial to cross-examine the witness, admission of the witness’s former testimony does not violate the defendant’s constitutional rights of confrontation and due process. (Ohio v. Roberts (1980) 448 U.S. 56, 68-70 [65 L.Ed.2d 597, 609-610, 100 S.Ct. 2531]; People v. Hovey (1988) 44 Cal.3d 543, 564 [244 Cal.Rptr. 121, 749 P.2d 776]; People v. Enriquez (1977) 19 Cal.3d 221, 235 [137 Cal.Rptr. 171, 561 P.2d 261, 3 A.L.R.4th 73].) Defendant urges this court to preserve a defendant’s confrontation rights by adopting a judicially declared rule of practice in capital cases (see People v. Aranda (1965) 63 Cal.2d 518, 530 [47 Cal.Rptr. 353, 407 P.2d 265]) that the former testimony of an accomplice who asserts his Fifth Amendment privilege is inadmissible at trial. In support, he argues that cross-examination at the preliminary hearing cannot compensate for lack of confrontation at trial because the nature and objective of the two proceedings differ significantly. (See Barber v. Page (1968) 390 U.S. 719, 725 [20 L.Ed.2d 255, 260, 88 S.Ct. 1318]; People v. Stritzinger (1983) 34 Cal.3d 505, 516 [194 Cal.Rptr. 431, 668 P.2d 738] [quoting Barber].) It is established, however, that competing interests “may warrant dispensing with confrontation at trial” (Ohio v. Roberts, supra, 448 U.S. at p. 64 [65 L.Ed.2d at p. 606]) and counterbalancing a defendant’s interest in confrontation is the state’s “strong interest in effective law enforcement.” (Ibid.; see People v. Ogen (1985) 168 Cal.App.3d 611, 616 [215 Cal.Rptr. 16].) In permitting use of the former testimony of an unavailable witness, the courts have struck an appropriate balance between competing interests. (Ohio v. Roberts, supra, at pp. 64-66 [65 L.Ed.2d at pp. 606-608]; see also Barber v. Page, supra, 390 U.S. at p. 722 [20 L.Ed.2d at pp. 258-259].) We see no reason to strike a different balance in a capital case. Defendant asserts that “trial-by-transcript” in a capital case, especially where the source of the transcript—an accomplice—has been recognized as inherently untrustworthy, contravenes basic notions of fairness and the need for heightened reliability in the fact-finding process that may lead to a defendant’s death. The issue of Crenshaw’s reliability, however, was fully presented to the jury through defense counsel’s extensive cross-examination at the preliminary hearing, which, inter alia, disclosed that Crenshaw was awaiting trial on murder charges in the White case and on special circumstance murder charges in the present case; defense counsel’s argument, which fully explored Crenshaw’s accomplice status and possible motive to lie; the prosecutor’s acknowledgment that Crenshaw was trying to exculpate himself; and the court’s instructions relating to accomplice testimony (e.g., CALJIC Nos. 3.11 [corroboration necessary], 3.12 [sufficiency of corroborating evidence], 3.18 [viewing testimony with distrust]). Nor was this a “trial by transcript”: Crenshaw’s former testimony was amply corroborated by the circumstantial evidence, the testimony of Laughlin that defendant admitted killing Benham and defendant’s own testimony admitting he was present with Benham and that he robbed and kidnapped her. Use of the former testimony was not error. II. Special Circumstance Issues A. Intent to Kill. The jury was instructed that to find the charged felony-murder special circumstances true it must find the murder was committed in the course or furtherance of the robbery and/or kidnapping for robbery, except, if defendant was not the actual killer, then it must find defendant intentionally aided or abetted the actual killer in the commission of the murder and “have intended that the killing take place.” Relying on Carlos v. Superior Court (1983) 35 Cal.3d 131 [197 Cal.Rptr. 79, 672 P.2d 862] and People v. Garcia (1984) 36 Cal.3d 539 [205 Cal.Rptr. 265, 684 P.2d 826], overruled in People v. Lee (1987) 43 Cal.3d 666, 676 [238 Cal.Rptr. 406, 738 P.2d 752], defendant argues that the felony-murder special-circumstance findings must be set aside because the court erroneously instructed that intent to kill was required only if defendant were not the actual killer. In People v. Anderson (1987) 43 Cal.3d 1104 [240 Cal.Rptr. 585, 742 P.2d 1306] we reconsidered our Carlos decision, supra, 35 Cal.3d 131. We concluded the court need instruct on intent to kill as an element of the felony-murder special circumstance only if there is evidence from which the jury could find the defendant was an accomplice rather than the actual killer. (43 Cal.3d at p. 1147.) The court’s instructions were proper under Anderson. Defendant maintains the principles of fair notice inherent in ex post facto and due process analysis prohibit the retroactive application of Anderson. We have recently considered and rejected this argument in People v. Poggi (1988) 45 Cal.3d 306, 326-327 [246 Cal.Rptr. 886, 753 P.2d 1082], As in Poggi, defendant stands convicted of a murder that preceded our decision in Carlos, supra, 35 Cal.3d 131. Carlos itself concluded the statute was ambiguous with respect to the requirement of intent to kill for a felony-murder special circumstance. (See Anderson, supra, 43 Cal.3d at p. 1143.) We therefore reject defendant’s fair-notice argument. B. Prior-murder-conviction Special Circumstance. As proof of the prior-murder-conviction special-circumstance charge, the prosecutor introduced documentary evidence that in 1982 defendant was convicted of the first degree murder of White. Relying on Carlos v. Superior Court, supra, 35 Cal.3d 131 dead People v. Turner (1984) 37 Cal.3d 302 [208 Cal.Rptr. 196, 690 P.2d 669], defendant contends the prior-murder-conviction special circumstance must be set aside because there was no finding in either the present or prior case that he intended to kill. Any contrary result, he maintains, would irrationally distinguish between defendants whose multiple murders were joined for trial (see Turner, supra, at pp. 328-329, requiring intent to kill in at least one of two joined felony murders) and those whose offenses were severed or, as here, jurisdictionally precluded from being jointly tried (§ 777; People v. Bradford (1976) 17 Cal.3d 8, 14 [130 Cal.Rptr. 129, 549 P.2d 1225]). Defendant also maintains the prior-murder-conviction special-circumstance finding is invalid because the underlying murder occurred subsequent to the present offense. In People v. Hendricks (1987) 43 Cal.3d 584, 596 [238 Cal.Rptr. 66, 737 P.2d 1350], we held intent to kill is not an element of the prior-murder-conviction special circumstance. Defendant’s concern that this holding irrationally distinguishes between defendants is answered by Anderson, supra, 43 Cal.3d 1104. In Anderson we rejected the reasoning of Carlos, supra, 35 Cal.3d 131, and Turner, supra, 37 Cal.3d 302, and determined intent to kill is not an element of the felony-murder or the multiple-murder special circumstance unless the defendant was an aider or abettor and not the actual killer. (43 Cal.3d at pp. 1147, 1149-1150.) As indicated, the jury in the instant case was instructed in compliance with Anderson. Thus, application of the prior-murder-conviction special circumstance to render defendant death-eligible results in no irrational distinction between defendants tried jointly and those whose offenses are separately tried. Defendant’s further contention that the prior murder must have preceded the present offense was rejected in People v. Hendricks, supra, 43 Cal.3d 584, 595-596. “The order of the commission of the homicides is immaterial.” {Id. at p. 596.) III. Penalty Phase Issues A. Failure to Instruct on Informant's Testimony. Observing that jailmate Laughlin’s testimony as to defendant’s confession was “some of the most damning evidence” concerning defendant’s role in the Benham crimes and the only direct evidence of his state of mind with respect to Benham’s murder, defendant asserts that in a capital case due process requires the court sua sponte to instruct the jury to view the testimony of an informant with caution. In People v. Hovey, supra, 44 Cal.3d 543, 565-566 we declined to impose a requirement of sua sponte cautionary instructions on informant testimony. We adhere to that ruling here. B. Refusal to Re-voir Dire the Jury. After completion of the guilt phase of trial, defendant moved for a new jury pursuant to section 190.4, subdivision (c) or, in the alternative, that the jury be voir dired to determine if there were good cause why any juror could not sit in the penalty phase. Both motions were based on the assertion that in light of the inflammatory evidence presented at the guilt phase and the relatively short time it took the jury to reach a verdict (three to four hours), there was a likelihood the verdict was based on passion and the jury therefore could not approach the question of penalty with an open mind. The trial court denied the motions on grounds there was no legal basis for voir dire of the sitting jurors and a new jury would in any event hear the same evidence as the guilt phase jury. Section 190.4, subdivision (c) provides in pertinent part: “If the trier of fact which convicted the defendant of a crime for which he may be subject to the death penalty was a jury, the same jury shall consider . . . the penalty to be applied, unless for good cause shown the court discharges that jury in which case a new jury shall be drawn.” Defendant maintains the authority to voir dire the jury is implicit in the section, as voir dire is the only meaningful way to determine whether the jurors could consider the penalty phase evidence with open minds and not automatically vote for death by reason of the passions engendered in the first phase of trial. As we observed in People v. Gates (1987) 43 Cal.3d 1168, 1199 [240 Cal.Rptr. 666, 743 P.2d 301], there is no direct authority on the meaning of “good cause” in the context of impanelling a new penalty phase jury. Neither is there any authority concerning how good cause may be shown. Nevertheless, we believe that defendant’s assertions of possible juror bias in this case, based on the inflammatory nature of the guilt phase evidence and the promptness of the verdict, were insufficient to impose any duty of inquiry on the court. First, since the evidence in every capital case is likely to be somewhat inflammatory, defendant’s argument, extended to its logical conclusion, would require the court routinely to re-voir dire the jury. This clearly is not the intent of the statute. (Cf. People v. Balderas (1985) 41 Cal.3d 144, 204-205 [222 Cal.Rptr. 184, 711 P.2d 480] [due process does not require separate penalty jury].) Second, as the trial court observed, the “inflammatory” guilt phase evidence would be presented to the penalty phase jury in any case. That the guilt phase jury initially heard the evidence without mitigating evidence is, like the admission of inflammatory evidence itself, common to all capital cases and thus cannot be sufficient cause for discharge. In sum, defendant’s showing raised no duty on the part of the court to question the jurors. (See People v. Ainsworth (1988) 45 Cal.3d 984, 1028-1029 [248 Cal.Rptr. 568, 755 P.2d 1017]; People v. Gates, supra, 43 Cal.3d at p. 1199.) C. Evidentiary Errors. Observing that the jury spent more than a day in deliberations (six hours the first day, two hours the second) and requested the rereading of the testimony of three witnesses (Crenshaw, Laughlin and defendant), defendant maintains the jury found the choice of appropriate penalty to be a close question. Given this asserted delicate balance between evidence in favor of life and that in favor of death, defendant contends the following three evidentiary errors require reversal of the penalty verdict. 1. Impeachment of Terry Caylor. At the penalty phase Caylor impeached Laughlin, the jailhouse informer who testified defendant had confessed to the Benham, White and Rankin murders. According to Caylor, Laughlin admitted he was lying about defendant’s involvement; he stated he had an agreement with Crenshaw that he would testify against defendant and indicated his testimony would result in dismissal of the charges pending against him. At the outset of direct examination defense counsel elicited from Caylor that he had previously been convicted of a felony, he was presently awaiting trial on another matter, and he had previously been represented by defense counsel, but had discharged him so he could represent himself. On cross-examination the prosecutor elicited that Caylor had been convicted of the felonies of robbery, rape and lewd conduct; he was awaiting trial on an escape charge; he was representing himself; and he had escaped from Patton, a mental institution. Defense counsel failed to object. Defendant contends that pursuant to People v. Woodard (1979) 23 Cal.3d 329, 335 [152 Cal.Rptr. 536, 590 P.2d 391], the prosecutor improperly impeached Caylor with the rape and lewd conduct convictions, which had no bearing on Caylor’s truthfulness. Because the charged crimes occurred prior to the adoption of Proposition 8, Woodard governs. (People v. Smith, supra, 34 Cal.3d 251.) Consequently, although the challenged evidence was related in general to matters raised on direct, had defense counsel objected admission of the evidence likely would have been error: neither the nature of Caylor’s rape and lewd conduct convictions nor the nature of his pending escape charge (as distinguished from the fact he was in jail awaiting trial) had any bearing on his credibility (see People v. Rist (1976) 16 Cal.3d 211, 221 [127 Cal.Rptr. 457, 545 P.2d 833] [rape]; People v. Holt (1984) 37 Cal.3d 436, 454-455 [208 Cal.Rptr. 547, 690 P.2d 1207] [escape]) or any other identified issue, and the Attorney General has made no attempt to show how Caylor’s mental problems or election to represent himself had any bearing on his testimony or ability to perceive the matters testified to (see Evid. Code, § 780, subd. (d)). Although counsel’s failure to object waives the issue in the context of evidentiary error (see Evid. Code, § 353), the issue is reviewable in the context of whether counsel provided ineffective assistance, discussed post at pages 33-34. (See People v. Fosselman, supra, 33 Cal.3d 572, 581.) 2. Implied Existence of Uncalled Adverse Witnesses. Eugene Mazza, defendant’s former manager in the newspaper delivery business, testified to defendant’s reliability, conscientiousness and good character. On cross-examination the prosecutor asked if he “became aware that other persons had also been contacted for references,” and if he would know “if some people were called and just didn’t want to come in and testify?” Defendant maintains the sole purpose of this questioning was improperly to insinuate to the jury that there existed untold witnesses who knew defendant and were interviewed by the defense team, but had refused to speak on his behalf. (See People v. Wagner (1975) 13 Cal.3d 612, 619-620 [119 Cal.Rptr. 457, 532 P.2d 105]; cf. People v. Bolton (1979) 23 Cal.3d 208, 212 [152 Cal.Rptr. 141, 589 P.2d 396] [improper argument].) The questions were improper. In light, however, of the 24 witnesses who in fact did testify in defendant’s behalf, including friends, family, teachers, neighbors, counselors, a priest and a state court justice, the error manifestly was harmless under any standard. (Cf. People v. Bolton, supra, 23 Cal.3d at p. 214.) 3. Prison Gang Activity and Appeal to Racial Prejudice. - Defendant maintains that through the improper introduction of evidence of prison gang activity, the prosecutor appealed to racial prejudice and implied defendant’s future dangerousness. Defendant first cites the prosecutor’s questions to a prison guard whether he was aware of gang activity at the prison and the existence of Black gangs that occasionally harmed White inmates. These questions were asked in the context of attempting to rehabilitate prosecution witness Smith, whose testimony concerning defendant’s involvement in a jail sodomy had been impeached by the guard’s testimony on direct that Smith had given inconsistent statements about the incident. The prosecutor’s inquiry about gangs arguably was improper: although the prosecutor could show victim Smith’s fear of retaliation, as in fact he did (see fn. 7, ante), absent a showing of gang involvement in the sodomy or gang practice (as opposed to individual or general inmate practice) to engage in retaliation, the existence of prison gangs and the harm done White inmates by Black gangs was irrelevant and potentially prejudicial. (Cf. People v. Cardenas (1982) 31 Cal.3d 897, 904-905 [184 Cal.Rptr. 165, 647 P.2d 569] [plur. opn.]; People v. Perez (1981) 114 Cal.App.3d 470 [170 Cal.Rptr. 619].) Defense counsel, however, failed to object. Because, in our opinion, a timely objection and admonition, when the district attorney first asked about gang activity at the prison, would have cured the effect of any impropriety and have deterred further prosecutorial inquiry into such activity without a foundation showing its relevance, the issue is waived. (People v. Murtishaw (1981) 29 Cal.3d 733, 758-759 [175 Cal.Rptr. 738, 631 P.2d 446].) This being so, the remaining question is whether defense counsel’s failure to object constituted ineffective assistance, discussed post at pages 33-34. Defendant next complains about the prosecutor’s reference to prison gang activity in his cross-examination of psychologist Dr. Craig Rath, who had testified that defendant, under “very specific conditions,” might mature in the structured prison environment, where life prisoners achieve a stable “status quo.” The prosecutor asked Dr. Rath whether the “status quo” can often take the form of criminal activity by gangs and whether he was aware that often entree into a gang is achieved by killing another inmate. This evidence, defendant maintains, served only to raise the possibility of defendant’s future dangerousness and thus was inadmissible as irrelevant to any aggravating factor. (People v. Boyd (1985) 38 Cal.3d 762, 773-776 [215 Cal.Rptr. 1, 700 P.2d 782]; see People v. Murtishaw, supra, 29 Cal.3d at pp. 767-768.) Although evidence of future dangerousness is inadmissible in the prosecution’s case-in-chief (Boyd, supra, 38 Cal.3d at pp. 775-776; Murtishaw, supra, 29 Cal.3d at pp. 767-768), such evidence may be introduced in rebuttal where, as here, the defense has raised the issue of defendant’s performance in prison and has presented evidence he would live a law-abiding life in a prison environment (Boyd, supra, at p. 776). (See People v. Gates, supra, 43 Cal.3d 1168, 1211; People v. Rodriguez (1986) 42 Cal.3d 730, 791 [230 Cal.Rptr. 667, 726 P.2d 113]; cf. Jurek v. Texas (1976) 428 U.S. 262, 274-276 [49 L.Ed.2d 929, 939-941, 96 S.Ct. 2950] [no constitutional impediment to evidence of future dangerousness].) Here, moreover, the evidence was directed not to defendant’s future dangerousness as such, but rather to the nature of the prison environment—an environment the defense had sought to prove would foster defendant’s maturity and stability. The questioning, as the Attorney General observes, served to cross-examine Dr. Rath on the impression he had left with the jury that prison was a tranquil place where defendant could get counseling and psychiatric care, which would enable him to control the impulsivity that had contributed to his past criminal behavior. (See Evid. Code, §§ 721, subd. (a), 761; cf. Brown v. Colm (1974) 11 Cal.3d 639, 646 [114 Cal.Rptr. 128, 522 P.2d 688].) 4. Denial of Due Process. Asserting that the prosecution’s routine use of “professional snitches” like Laughlin to persuade juries in capital cases is disturbing of itself, defendant contends the prosecutor’s further use in this case of improper means to destroy the credibility of the witness (Caylor) who showed Laughlin to be a liar constituted a denial of due process. As a further denial of due process, defendant cites the prosecutor’s “gratuitous invocation of the image of [B]lack prison gangs attacking hapless [Wjhites,” an image that assertedly exploited the risk of racial prejudice inherent in this case, involving as it does a Black man convicted of killing a White woman in circumstances having sexual overtones. Defendant’s due process argument rests on the premise the prosecutor engaged in deliberate misconduct. The record is to the contrary. During the guilt phase of trial, when the defense proposed to have defendant’s cellmates impeach Laughlin, the prosecutor specifically noted he had no background information on the witnesses and assumed they had all been convicted of felonies. He asked for assurance there would be no motion for a mistrial if he inquired of that without having the necessary proof. Defense counsel acceded, stating, “I think they will freely admit that they are hardcore criminals.” Thereafter the prosecutor, without objection, asked each of the inmate witnesses what felonies he had been convicted of; as to one prisoner, defense counsel did the same. On this record, and absent a showing of any different understanding at the penalty phase of trial, defendant’s assertion of prosecutorial misconduct in cross-examination of Caylor is meritless. Nor was the prosecutor’s reference to Black gang activity misconduct. The reference was in the context of rehabilitating witness Smith who, according to the defense’s prison-guard witness, had given prior inconsistent statements concerning defendant’s involvement in the sodomy attack against him and had attributed his change of story to confusion and fear. Because defendant is Black and Smith evidently is White, the prosecutor could reasonably have believed the asserted attacks of Black gangs against White inmates were relevant to Smith’s fear of retaliation if he testified against defendant. We thus reject defendant’s due process contentions. 5. Waiver and Ineffective Assistance of Counsel. Defendant maintains that if we determine counsel’s failure to object waived the errors in admitting evidence of Terry Caylor’s criminal background and of Black prison gang activity, such failure denied him the effective assistance of counsel. A defendant who on appeal asserts a claim of ineffective assistance has the burden to show counsel failed to perform as a reasonably competent attorney acting as a diligent advocate and that counsel’s deficiencies prejudiced his case. (People v. Pope, supra, 23 Cal.3d 412, 425; People v. Fosselman, supra, 33 Cal.3d 572, 584; see Strickland v. Washington, supra, 466 U.S. 668; People v. Ledesma (1987) 43 Cal.3d 171, 216-217 [233 Cal.Rptr. 404, 729 P.2d 839].) We have observed that a mere failure to object to evidence seldom establishes counsel’s incompetence. (People v. Ghent (1987) 43 Cal.3d 739, 772 [239 Cal.Rptr. 82, 739 P.2d 1250].) Assuming arguendo, however, that a reasonably competent attorney would have objected to the challenged evidence and, further, that there could be no justifiable tactical reason for counsel’s failure to object (cf. Pope, supra, at pp. 426, 428; Ghent, supra, at p. 773), defendant still must show counsel’s omissions were prejudicial. Counsel’s failure to prevent the improper impeachment of Caylor was prejudicial, defendant maintains, because Caylor’s testimony, if believed, discredited Laughlin, whose testimony provided the only direct evidence defendant, and not Crawford, was the perpetrator of the crimes. We disagree. Even without evidence of Caylor’s felony convictions for rape and lewd conduct and his pending escape charges, the jury was aware that Caylor, like Laughlin himself, was a convicted felon awaiting trial on new charges. The specifics of his criminal history could not have made an appreciable difference. Indeed, arguably it was less prejudicial for the jury to know the nature of Caylor’s priors and pending charges than to leave the question open to speculation. (Cf. People v. Rollo (1977) 20 Cal.3d 109, 119 [141 Cal.Rptr. 177, 569 P.2d 771].) During the guilt phase, moreover, the jury had heard and evidently rejected similar impeaching evidence concerning Laughlin’s asserted manufacture of his testimony. The details of Caylor’s criminal background could not in the circumstances have been determinative of the jury’s resolution of the issue of Laughlin’s credibility. Admission of evidence of Black prison gang activity, although arguably improper, likewise was nonprejudicial. As indicated, evidence of prison gang activity in general was properly admitted in the context of describing the environment defendant would interact with were he sentenced to life without possibility of parole, an issue raised by the defense. The single reference to Black gang activity occurred in the course of cross-examination of a prison guard about inmate Smith’s fear of retaliation for reporting the sodomy attack. Dr. Rath, testifying for the defense concerning defendant’s likely behavior in prison, twice stated that defendant is prone to be a “loner,” not a gang joiner—thus neutralizing in part any prejudicial effect of the improper reference. Dr. Rath further testified that defendant is a sociopath with attention-deficit disorder whose problems of hyperactivity, irritability and impulsivity would continue to manifest themselves, and that it would be consistent with defendant’s personality to try to escape. In light of the above testimony and the overwhelming aggravating evidence—particularly that during defendant’s last escape from jail he engaged in a crime and murder spree that left four people dead, and immediately after his commitment to prison for the White murder he engaged in assaultive sexual behavior—the arguably improper reference to Black gangs could not have affected the verdict. Throughout most of the lengthy trial, counsel performed as a vigorous and capable advocate. We conclude that even assuming counsel’s failure to object to the challenged evidence was unreasonable, the prejudice defendant suffered, if any, does not warrant setting aside his death sentence. (Strickland v. Washington, supra, 466 U.S. at pp. 694-695, 698-699 [80 L.Ed.2d at pp. 698, 700-701]; People v. Fosselman, supra, 33 Cal.3d at p. 584; People v. Pope, supra, 23 Cal.3d at p. 423.) D. Excusing Crenshaw From Testifying. Defendant’s crime partner, Crenshaw, testified for the prosecution at the preliminary hearing, but invoked his privilege against self-incrimination when called by the prosecution at the guilt phase of trial, although he testified briefly for the defense. (Ante, fn. 4, p. 23.) At the penalty phase, defendant sought to call Crenshaw again, proposing to ask if he had shot White, the victim in the prior-murder special circumstance. The trial court, informed by Crenshaw’s counsel he would instruct his client not to answer the question, ruled Crenshaw need not testify, based on the assumption he would invoke his privilege against self-incrimination if called. The court ruled further that “based on the offer of proof,” the subject matter of Crenshaw’s proposed testimony was either not relevant or could be proved by some other means. Defendant contends these rulings were error. We first observe that defense counsel did not object to the challenged procedure, but rather, acquiesced in it; hence defendant may not complain on appeal. (People v. Harris (1979) 93 Cal.App.3d 103, 118 [155 Cal.Rptr. 472].) In any event, the court’s ruling that Crenshaw need not take the stand to reassert his Fifth Amendment privilege was not error. Crenshaw had previously exercised the privilege as to all events between March 19, 1981, and March 24, 1981. (See ante, fn. 4, p. 23.) White’s murder occurred during those dates. Crenshaw’s counsel confirmed he would advise his client not to respond to the proposed question. In these circumstances, the court properly found there was no reason to have Crenshaw personally reassert the privilege. None of the cases relied on by defendant is apposite because in none did the witness, as here, personally assert the privilege at trial. (E.g., People v. Kynette (1940) 15 Cal.2d 731, 747 [104 P.2d 794]; People v. Harris, supra, 93 Cal.App.3d at p. 117; see also People v. Ford (1988) 45 Cal.3d 431, 435-436 [247 Cal.Rptr. 121, 754 P.2d 168].) Although defendant would have us equate the separate phases of trial to separate “proceedings,” so as to require a witness to invoke the privilege at each (see People v. Kynette, supra), we decline to do so. Likewise meritless is defendant’s argument that absent Crenshaw’s actual reinvocation of the privilege at the penalty phase, the court was in no position to rule whether the privilege applied. Although Crenshaw, based on his guilty plea, had been convicted and sentenced for the White murder and evidently had failed to appeal (cf. People v. Lopez (1980) 110 Cal.App.3d 1010, 1021 [168 Cal.Rptr. 378] [privilege survives pending resolution of appeal]), thus rendering his conviction final, the same was true at the guilt phase. In both instances, he had yet to be tried for the Benham murder, in which trial it was more than likely the prosecution, as in defendant’s trial, would seek to introduce evidence of the White murder for purposes of establishing Crenshaw’s guilt. Because a response to defense counsel’s question whether he shot White thus could lighten the district attorney’s burden of proof, Crenshaw was privileged to refuse to answer. (See Prudhomme v. Superior Court (1970) 2 Cal.3d 320, 326 [85 Cal.Rptr. 129, 466 P.2d 673].) We conclude, therefore, the court did not err in determining Crenshaw’s invocation of the privilege extended to the defense’s proposed penalty phase question. (See People v. Ford, supra, 45 Cal.3d at p. 441.) Nor did the court err in its relevan
