ORDER LEWIS A. KAPLAN, District Judge. Plaintiff and defendants cross-move for partial summary judgment. In an extensive and thorough report and recommendation dated August 28, 2009 (the “R & R”), Magistrate Judge Michael H. Doling-er recommended that defendants’ motion be granted in part and denied in part and that plaintiffs motion be denied. Both sides have objected to the R & R at least in certain respects. Having carefully considered the matter, the objections are overruled. Plaintiffs motion for partial summary judgment [DI 112] is denied in all respects. Defendants’ cross-motion [DI 120] is granted to the extent that plaintiffs Monell claim against the City and his claims for assault and battery, defamation, intentional infliction of emotional distress, and negligence all are dismissed. Their cross motion is denied in all other respects. The Clerk shall terminate docket item 151, the defendants’ objections to the R & R, which were improperly docketed as a motion. SO ORDERED. REPORT & RECOMMENDATION MICHAEL H. DOLINGER, United States Magistrate Judge. TO THE HONORABLE LEWIS A. KAP-LAN, U.S.D.J.: Plaintiff Yang Feng Zhao commenced this lawsuit against a number of New York City police detectives and the City of New York in the wake of the December 2006 dismissal of a murder charge filed against him more than one year earlier. In his amended complaint he sues two police detectives (Dets. Nga Cheung Ng and Billy Milan), a police sergeant (Sgt. Brian Con-Ion), and the City, contending that they arrested him in October 2005 for a 2001 night club murder, that they did so without probable cause, and that shortly after his arrest they used physical violence, threats, and psychological coercion to extract his consent to a manufactured, false confession. He alleges further that they used the false confession as well as lies to the District Attorney’s Office of Queens County to procure an indictment of him for that murder. As a result, he says, he spent nearly a year in jail, after which time he was released and the charge dismissed based upon the prosecutor’s representation to the court that he was not involved in the murder. Based on these allegations plaintiff asserts federal and state-law claims for false arrest and malicious prosecution, federal claims of excessive force and violation of his right not to incriminate himself, as well as state-law claims for assault, battery, intentional infliction of emotional distress, defamation, and negligence. He also asserts a Monell claim against the City for pursuing practices or policies that countenance the types of constitutional violations alleged here, as well as for a failure to train and supervise police personnel in conducting investigations, assessing evidence, undertaking interrogations, and handling so-called cold cases. He seeks an award of compensatory and punitive damages against the individual defendants and compensatory damages from the City. At the conclusion of discovery, both defendants and plaintiff have moved for partial summary judgment. Defendants seek dismissal of (1) the Monell claim, (2) the federal false-arrest claim, (3) the federal excessive-force claim, and (4) all of the state-law claims, thus leaving the federal malicious-prosecution and self-incrimination claims for trial. Plaintiff of course opposes defendants’ motion, and he asks for partial summary judgment on his federal and state-law claims for false arrest, seeking a ruling that the police arrested him without probable cause and that the City is liable for these wrongs. In addition, plaintiff has requested that, if the state malicious-prosecution claim is deemed unexhausted under the New York General Municipal Law, as defendants argue in their papers, he be given leave to file an out-of-time administrative notice of claim under New York Gen. Mun. Law § 50-e. For the reasons that follow, we recommend that defendants’ motion be granted in part and denied in part. We further recommend that plaintiffs motion be denied in its entirety. The Basic Facts In the early morning hours of December 11, 2001, at the Gold Box Karaoke Club in Queens, a club employee named Danny Cabezas was fatally stabbed by a patron of the club. (Pl.’s Mot. for Summ. J. Ex. (“PX”) 1). Cabezas was working as a bouncer that night (Huang Dep. 8), and shortly before the stabbing had been involved in an altercation with a group of patrons. (N.Y.C 706; PXs 5-6; Lau Dep. 49-55; Romano 5/14/08 Dep. 218-19; Milan Dep. 156-57, 186; Zhao Dep. 119-23). The events surrounding the stabbing, including the physical altercations between Cabezas and the patrons as well as the departure of that group of patrons after the stabbing, were recorded in part by several video cameras that were operating that night at the club. (See, e.g., NYC 706, 707, 708; PX31). Within hours of the incident the police interviewed a number of club employees. The manager of the club, George Huang, recounted that shortly before the killing, he was in a room at the club when he heard a noise, left the room, and observed Cabezas in the main hall area of the club, fighting with a number of male and female Chinese patrons who had been in Room 6 of the club. Huang reported that he had broken up the fight, and that Cabezas had then escorted those patrons out of the club. According to Huang, shortly afterward Cabezas returned along the hall from the direction of the exit, clutching his chest, and then fell to the floor near Room 9. Huang further reported that two men from the group in Room 6 had remained behind, looking for their shoes, while Cabezas was escorting the others towards the exit. Only after Cabezas returned, already wounded, did the two men leave, and they had nothing in their hands. (PX 24; Wilkinson Dep. 32-37). It later transpired that plaintiff Zhao was one of these two men. (Zhao Dep. 124-27; Oct. 6, 2008 letter to the court from Eric W. Siegle, Esq. (“Siegle Letter”) Ex. 2 at 34-38). Ms. Yun Chen, a waitress, recounted to the police that Huang and a club employee named Peter (apparently assistant manager Peter Yee) had stopped a fight between Cabezas and some men who had been in Room 6. She stated that Cabezas had then escorted those patrons towards the area of the stairs where an exit led out of the club. Moments later, she said, she saw him return from the stairway area, holding his chest and bleeding from the stomach area. He then fell to the ground in front of Room 9. (PXs 20-21; Ng 10/16/07 Dep. 65-68, 71-73, 95-98). Ms. Chen did not see the stabbing itself. (Ng 10/16/07 Dep. 90-91). Another waitress, Yu Hua Huang, recounted that she had heard some yelling and had looked out into the hall and seen some men descending the stairs. Shortly thereafter Cabezas returned from the area of the exit, clutching his chest. He then fell near her. (PX 22; Maline Dep. 69-74, 76-86). Ms. Huang also did not see the stabbing. (Maline Dep. 91-92). The police also interviewed Peter Yee. He reported that he had been in a room playing cards with Huang when they heard a banging sound and overheard Cabezas arguing with some Asian men. They ran from the room into the hall and saw Cabe-zas fighting with approximately six men. Yee and Huang stopped the fight and told Cabezas to walk away and leave the men alone. According to Yee, Cabezas walked to the end of the hallway, where more fighting then erupted between him and the other men, who apparently attacked him. Yee ran towards the group to stop the fight and saw one Asian man, wearing a white ski jacket, leap up and strike Cabe-zas in the chest, possibly stabbing him. After Yee stopped this fight, Cabezas walked back down the hall and collapsed, bleeding profusely. (PX 23; S. Rivera Dep. 19-23, 38). Both Huang and Yee spoke further with the investigating police (who included defendant Ng) at the 109th precinct that same night. At that time they observed some of the club videotapes. Watching the tapes, Yee recounted the second fight, which he said had occurred around the stairwell that led to an exit from the club. He reported again that a man had jumped past him and lunged at Cabezas, and this time he identified that man on the video as a man who was long-haired and wearing a white T-shirt. (PXs 30-31; Ng 10/16/07 Dep. 125-28; Ng 5/23/08 Dep. 220-23). Huang also confirmed that the second fight had occurred by the stairwell and that Cabezas had then staggered down the main hall, where he collapsed in front of Room 9. (PX 17; Huang Dep. 16-17, 24-27,120-21). In the wake of these interviews and the review of the available videotapes, the police then investigating the murder inferred that the stabbing had taken place in a small area at the stairwell, near the second-floor entrance to the club, which was at the far end of the main hallway. They further inferred that the assailants were the men with whom Cabezas had fought minutes before, and that Cabezas, after being stabbed, had staggered down the main hallway for a short distance before collapsing. (See, e.g., Romano 5/14/08 Dep. 213-14, 216; Romano 10/18/07 Dep. 81-86; Romano 4/9/08 Dep. 229-31; Casazza Dep. 99-101; PXs 6-7). This version was reiterated by one of the investigators, Det. Vincenzo Romano, when he spoke to the press and asked, through news outlets, for public assistance in identifying the assailants. (Romano 5/14/08 Dep. 200-02; Romano 10/18/07 Dep. 81-86; PXs 6-7, 12). This version of events appeared to be supported not only by the statements of the four eyewitnesses, but also by the videotapes obtained from the club. One tape, NYC 706, labeled “main hallway” and “fight,” shows what appears to have been the initial fight in the main hallway between Cabezas and a number of Asian men, followed by the termination of the encounter through the intervention of Huang and Yee. During and after the first fight the tape shows a number of people gathering in the hallway around the fight, but it is hard to discern what each person is doing. On the same tape Cabezas is depicted walking down that hall in the direction of the stairwell and second-floor exit, either preceded or followed by the men with whom he had just fought and some others. A few minutes later on the tape, two waitresses are seen in the hallway looking down the hall towards the stairwell and exit. At about that time Cabezas (or at least the top of his head) is seen coming away from that direction and seeming to stagger, with the waitresses looking at him with apparent concern. Cabezas then falls to the ground near Room 9, to the evident consternation of the waitresses, just as plaintiff is seen walking past him after having put on his shoes. (N.Y.C 706). On December 13, 2001, two days after the incident, Yee brought the police another videotape, which the police had overlooked, this one depicting the area around the stairwell, where the stabbing had apparently taken place. (Huang Dep. 123-24, 128). Indeed, Huang thought this the most important videotape for that reason. (Id. at 130-33). It was enhanced some days later by the police and designated “ + STAB.” (N.Y.C 708; see also PXs 38-39). The picture is not clear on the copies of NYC 708 provided to the court, but plaintiffs “3 camera view” video, copied from that tape and enhanced by a forensic video analyst, has a much clearer picture of the same video. The view shows a number of men who had been involved in the first fight appearing to leave the club, then returning and gathering in the area of the stairwell. It also seems to show a long-haired man in that area holding an object in his hand and lunging with the object into the area where Cabezas was apparently standing when he was stabbed. (Pl.’s “3 camera view” video; Romano 5/14/08 Dep. 213-14; Casazza Dep. 99-101; Ng 4/14/08 Dep. 16-21). Several days later the investigators created eleven still photographs from the various tapes, including five from the enhanced “ + STAB” tape. Among these were photographs of the long haired man holding an object at various points in the video. Based on the statements of the witnesses and the videotapes, Det. Romano concluded that this man had committed the stabbing. (Santaremo Dep. 7-29; Romano 5/14/08 Dep. 205-07, 213-16; PXs 5, 8-11,13-15, 30-31, 67-69). Included in the investigative file were two diagrams of the area of the club where the fights and stabbing had taken place. The markings on these diagrams correspond to the version of events described by the witnesses, including notations indicating that the stabbing had occurred at the end of the main hall near the stairwell. (PXs 42-43, 70). The case file also contained a “wanted” card for a man named Guang Ju Lin, prepared in December 2001 by a detective on the case, Det. John Sjoholm, indicating that Lin was viewed as “possible perp[etrator] — photo ID made” for the crimes of Murder and Gang Assault. (Sjo-holm Dep. 56-57; PXs 34-35). Sjoholm also prepared a card for plaintiff, labeling him only as a witness. (PXs 36, 37). On April 3, 2003 defendant Ng interviewed Zhao. Plaintiff told Ng that he had been present at the Gold Box on the night of the murder but did not know who had done the stabbing. (Ng 10/16/07 Dep. 132-34, 138). On the same day, Ng interviewed a man named Tong Chen. Tong stated that he had heard that a man named Guang Ju Lin had been involved in the killing, and that Lin had moved out of state. (Milan Dep. 311-12; PX 53). In 2003 and 2004, Det. David Casazza, who was also working on the Cabezas investigation, undertook to search for Lin, who was the only person positively identified by name as involved in the Cabezas homicide. In his efforts he was able to trace Lin to the West Coast, which was consistent with the report of Tong Chen and the later account of another witness, Yi King, who mentioned that Lin had gone to California. (Casazza Dep. 48-58/ PXs 48-50). Defendant Milan took over the investigation of the Cabezas murder in the Spring of 2004. He did so after receiving a phone call from Cabezas’s mother, who complained about the prolonged failure of the police to make an arrest. (Milan Dep. 65, 71-72). Milan obtained the case file, which contained, inter alia, DD-5s reflecting witness statements and investigatory steps taken by the earlier investigators, the videotapes, the crime scene diagrams, Det. Romano’s Homicide Notebook, still photos from the videotapes, wanted cards for Guang Ju Lin, a wanted card for Zhao as a “witness,” and witness statements. (Milan Dep. 72-75, 78, 124, 296, 324-25, 429-30, 491; PXs 20, 22-24, 35, 37, 52). Some time after taking over the case, Milan was contacted by Det. Laureano Rivera, who was conducting an investigation of an alleged extortion that involved some of the same men as were suspected of involvement in the Cabezas homicide. On September 23, 2004 Det. Rivera informed Milan that he had a confidential informant, named Lo San, who had told him that a man named “Taebo” had been present at the Gold Box Club on the night of the Cabezas murder, and that “Taebo” had been involved in the fight with Cabe-zas and had stabbed him. Rivera further reported to Milan that he believed that Lo San had obtained that information from another man, named Ah Jun, who had himself been present at the club at the time of the murder. (L. Rivera Dep. 33-34, 57-60; Milan Dep. 153, 373-74; PX 54). Indeed, Det. Rivera was able to identify Ah Jun on one of the videotapes from the club. (L. Rivera Dep. 31-41). Despite receiving this information, Milan apparently never sought to meet with either Lo San or his alleged source, Ah Jun. (Milan Dep. 153-54). In April 2005 Det. Rivera contacted Milan and informed him that an F.B.I. agent had located one of the men who appeared in the Gold Box videotapes from the night of the Cabezas murder. This was an individual named Zhao Ken Chen, also known as Yi King. On April 29, 2005, Milan met with Yi King, together with an F.B.I. agent who served as an interpreter. Milan recognized Yi King from the videotapes as having been at the Gold Box on the night of the murder. (Milan Dep. 143, 379-80, 390, 392, 397). According to the notes of the interpreter, Yi King reported that he had gone to the Gold Box with a man named Tai Bao; that Tai Bao, as well as two men known as Ah Gui and Ah Zhong, had been involved in a brawl with the bouncer; that Tai Bao had stabbed and killed the bouncer and then left the club; and that Tai Bao was in California. (Milan Dep. 143, 147-49, 397-99, 405-06; PX 56). Possibly as a result of these various contacts, the Cabezas investigatory file contained a photograph derived from the video tapes that was labeled “Long Hair being held back — Tai Bao.” (Mok Dep. 73; PX 3). In addition, at one point in the Spring of 2005 Milan noted to another investigator that he was seeking two individuals; one was Tai Bao, whom Milan identified from the video, and the other was Guang Ju Lin, also known as Ah Gui. (Mok Dep. 19-21, 43-44; Milan Dep. 145-55; Lau Dep. 28-29; PX 3). Given the information received from the various sources — including Lo San and Yi King — as well as the descriptions from the four club employees and the videotapes, it is not surprising that Milan apparently initially focused on Tai Bao. (See Milan Dep. 145-55; Mok Dep. 43-44; PX 3). It also bears noting that one of the club videotapes showed that Tai Bao had hurriedly left the club without wearing his jacket despite the cold winter weather that night. (Pl.’s “3 camera view” video; NYC 705; Reibstein Dep. 52; PX 23). Also Milan was aware that Tai Bao had apparently suffered a bloody nose in the first fight, thus underscoring both his role in the initial assault and a possible motive to exact more striking revenge on Cabezas. (Milan Dep. 155-58, 519-21; NYC 706). Although it appears that Milan made some efforts to locate Guang Ju Lin after he took over the case in 2004, he was unable to do so. (Milan Dep. 341-42, 344-45, 350-51; PX 58). In the course of those efforts, however, he did not pursue information reflected in the investigatory file. He did not speak with Dets. Sjoholm, Ca-sazza, or Santeramo, and did not talk to eyewitnesses such as Peter Yee. He also did not follow up on various leads in the case file, including a photo of Guang Ju Lin in Det. Romano’s Homicide Notebook, the crime scene diagram, or the enhanced photo stills from the videos. (Milan Dep. 284-89, 299-300, 320, 358, 361-62, 510-13, 516-17, 531, 544, 548, 550). In September 2005 Milan apparently decided that Zhao was the murderer, and as a result he sought permission from Sgt. Conlon to arrest plaintiff. The asserted basis for his conclusion was his review of a portion of the unenhanced video tape of the main hall at the time of the stabbing. As noted, this tape showed the top of Cabezas’s head when he apparently was staggering back from the area of the stairwell, as the waitresses watched, and then showed him fall as Zhao passed by him on his way to the stairwell. (Milan Dep. 163-65, 416; PX 706). The tape concededly did not show Zhao’s hand in contact with Cabezas and did not show Cabezas’s chest area. (Milan Dep. 165; Conlon Dep. 36-37). Even though at least one of the videos was of poor quality, Milan did not request any enhancing or cleaning up of the video. (Milan Dep. 92; Conlon Dep. 181). Milan showed this portion of the tape to Sgt. Conlon, stating that he believed it supported the notion that Zhao was the stabber. (Milan Dep. 416; Conlon Dep. 35-37). Milan discussed with both Conlon and Ng the fact that this theory was contradicted by the statements of the four club eyewitnesses, all of whom had reported seeing Cabezas walking from the stairwell area and then falling slowly in front of Room 9. (Milan Dep. 424-25). Conlon was also aware that Milan’s theory was inconsistent with the account by Peter Yee of the assault on Cabezas in the stairwell area and the report by George Huang that he had seen Cabezas wounded in the chest already when he returned from the same small area near the stairwell. (Conlon Dep. 158; Milan Dep. 425; Ng 4/14/08 Dep. 65-67). Having reviewed the portion of the videotape cited by Milan, Conlon authorized Milan to arrest Zhao. (Conlon Dep. 192-93). He based that decision solely on the videotape fragment that showed Zhao walking past Cabezas. (Conlon Dep. 35-37, 228). In authorizing the arrest, Conlon did not ask Milan to attempt to resolve the contradiction between his theory and all of the witness accounts nor did he require Milan to talk to the earlier investigators. (Conlon Dep. 31, 73-75, 161; Milan Dep. 425). He also did not watch all of the tapes available of the incident, and did not require that the tape he had viewed be enhanced to reveal the underscan, that is, the portion blocked by the screen border, even though the Police Department had that capacity. (McCourt Dep. 18, 81-82, 102-03; Conlon Dep. 181). In this regard we note that plaintiff undertook that task during this lawsuit, and as a result, when Milan viewed the same videotape, as enhanced, he conceded that Zhao had not stabbed Cabezas since the victim was already falling before coming into contact with Zhao. (Milan Dep. 180-83, 185, 262). On October 24, 2005 two detectives arrested Zhao without a warrant on a charge of having murdered Cabezas. (L. Rivera Dep. 13-18, 157; Zhao Dep. 130-35). Zhao has testified that he was taken to a Manhattan precinct and extensively questioned by Milan and Ng through an interpreter and then taken to a Queens precinct, where he was further interrogated. He reports that he consistently denied any involvement in the murder of Cabezas, that Conlon “patted” him on the face, and that Ng screamed at him, pushed his face down into the table, threatened him with physical harm (including prison assaults), and threatened his family with deportation. According to Zhao, Ng finally wrote out a confession, which included falsified errors for credibility, and Zhao signed and initialed it because of fear for his and his family’s safety. (Zhao Dep. 136-99; Sie-gle Letter Ex. 2 at 28-70 (plaintiffs testimony at 50-h hearing)). In dealing with the District Attorney’s Office, Milan never informed the prosecutors that he had spoken with Yi King, who had identified Tai Bao as the stabber. (Lomp Dep. 437). Also, apparently neither Milan nor Ng told the prosecutors about any of the other evidence developed by earlier investigators that suggested that the perpetrator was Tai Bao or that Guang Ju Lin was also involved. (Milan Dep. 503; Lomp Dep. 369, 431). Plaintiff remained in prison from October 25, 2005 until September 22, 2006. (PX 61). During this period a grand jury heard testimony from Det. Ng describing Zhao’s confession, and it returned an indictment charging him with murder. On December 18, 2006, the indictment was dismissed on the motion of the District Attorney. The prosecutor explained the request as being based on the fact that Zhao was not involved in the murder. (PX 62). This lawsuit followed. ANALYSIS Defendants’ motion targets all of plaintiffs claims except for the federal malicious-prosecution and self-incrimination claims. Plaintiff seeks summary judgment on his false-arrest claims. We first summarize the general summary-judgment standards and then address the claims at issue. A. Summary Judgment Standards The court may enter summary judgment only if it concludes that there is no genuine dispute as to the material facts and that, based on the undisputed facts, the moving party is entitled to judgment as a matter of law. Fed.R.Civ.P. 56(c); see, e.g., Celotex Corp. v. Catrett, 477 U.S. 317, 322-23, 106 S.Ct. 2548, 91 L.Ed.2d 265 (1986); Feingold v. New York, 366 F.3d 138, 148 (2d Cir.2004). It is axiomatic that the role of the court on such a motion “is not to resolve disputed issues of fact but to assess whether there are any factual issues to be tried, while resolving ambiguities and drawing reasonable inferences against the moving party.” Knight v. U.S. Fire Ins. Co., 804 F.2d 9, 11 (2d Cir.1986); see, e.g., Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 255, 106 S.Ct. 2505, 91 L.Ed.2d 202 (1986); Howley v. Town of Stratford, 217 F.3d 141, 150-51 (2d Cir.2000). The party moving for summary judgment bears the initial burden of informing the court of the basis for his motion and identifying those portions of the “pleadings, the discovery and disclosure materials on file, and any affidavits” that demonstrate the absence of a genuine issue of material fact. Fed.R.Civ.P. 56(c); see, e.g., Celotex, 477 U.S. at 322, 106 S.Ct. 2548; Koch v. Town of Brattleboro, 287 F.3d 162, 165 (2d Cir.2002). In making this judgment, the court must view the record in the light most favorable to the non-moving party. See, e.g., Hunter v. Bryant, 502 U.S. 224, 233, 112 S.Ct. 534, 116 L.Ed.2d 589 (1991); O’Hara v. Weeks Marine, Inc., 294 F.3d 55, 61 (2d Cir.2002). If the non-moving party has the burden of proof on a specific issue, the movant may satisfy his own initial burden by demonstrating the absence of evidence in support of an essential element of the non-moving party’s claim. See, e.g., Celotex, 477 U.S. at 322-23, 325, 106 S.Ct. 2548; PepsiCo, Inc. v. Coca-Cola Co., 315 F.3d 101, 105 (2d Cir.2002); Goenaga v. March of Dimes Birth Defects Found., 51 F.3d 14, 18 (2d Cir.1995). If the movant fails to meet his initial burden, however, the motion will fail even if the opponent does not submit any evidentiary materials to establish a genuine factual issue for trial. See, e.g., Adickes v. S.H. Kress & Co., 398 U.S. 144, 161, 90 S.Ct. 1598, 26 L.Ed.2d 142 (1970); Giannullo v. City of New York, 322 F.3d 139, 140-41 (2d Cir.2003). If the moving party carries his initial burden, the opposing party must then shoulder the burden of demonstrating a genuine issue of material fact. See, e.g., Beard v. Banks, 548 U.S. 521, 529, 126 S.Ct. 2572, 165 L.Ed.2d 697 (2006); Celotex, 477 U.S. at 322, 106 S.Ct. 2548; Santos v. Murdock, 243 F.3d 681, 683 (2d Cir.2001). In doing so, the opposing party cannot “rely merely on allegations or denials” of the factual assertions of the movant, Fed.R.Civ.P. 56(e)(2); see, e.g., Amaker v. Foley, 274 F.3d 677, 680-81 (2d Cir.2001), nor can he rely on his pleadings or on merely conelusory factual allegations. See, e.g., Weinstock v. Columbia Univ., 224 F.3d 33, 41 (2d Cir.2000). He must also “do more than simply show that there is some metaphysical doubt as to the material facts.” Matsushita Elec. Indus. Co. v. Zenith Radio Corp., 475 U.S. 574, 586, 106 S.Ct. 1348, 89 L.Ed.2d 538 (1986); see also Woodman v. WWOR-TV, Inc., 411 F.3d 69, 75 (2d Cir.2005). Rather, he must present specific evidence in support of his contention that there is a genuine dispute as to the material facts. See, e.g., Celotex, 477 U.S. at 324, 106 S.Ct. 2548; Scotto v. Almenas, 143 F.3d 105, 114 (2d Cir.1998); Rexnord Holdings, Inc. v. Bidermann, 21 F.3d 522, 525-26 (2d Cir.1994). To demonstrate a “genuine dispute,” the opposing party must come forward with sufficient evidence to permit a reasonable jury to return a verdict in his favor. See, e.g., Anderson, 477 U.S. at 242, 248, 106 S.Ct. 2505; Matsushita, 475 U.S. at 587, 106 S.Ct. 1348; Byrnie v. Town of Cromwell, Bd. of Educ., 243 F.3d 93, 101 (2d Cir.2001). Alternatively, if “the party opposing summary judgment propounds a reasonable conflicting interpretation of a material disputed fact,” summary judgment must be denied. Schering Corp. v. Home Ins. Co., 712 F.2d 4, 9-10 (2d Cir.1983); see also Rogath v. Siebenmann, 129 F.3d 261, 267 (2d Cir.1997); R.B. Ventures, Ltd. v. Shane, 112 F.3d 54, 59 (2d Cir.1997). When the parties have both filed motions for summary judgment, “a district court is not required to grant judgment as a matter of law for one side or the other.” Ricci v. DeStefano, 530 F.3d 88, 109-10 (2d Cir.2008). Rather, in these circumstances “the court must evaluate each party’s motion on its own merit s, taking care in each instance to draw all reasonable inferences against the party whose motion is under consideration.” Bronx Household of Faith v. Bd. of Educ. of the City of New York, 492 F.3d 89, 96-96 (2d Cir.2007) (citing Hotel Employees & Rest. Employees Union, Local 100 v. City of New York Dep’t of Parks & Recreation, 311 F.3d 534, 543 (2d Cir.2002)). If the material facts are in genuine dispute, then both motions must be denied. See, e.g., S.E.C. v. Lyon, 605 F.Supp.2d 531, 550 (S.D.N.Y.2009). B. Assessment of Defendants’Motion We first consider defendants’ motion. In doing so we do not adhere to the order in which defendants present their arguments, and instead first consider the federal claims asserted against the individual defendants. We then address the Monell claims and finally turn to the plaintiffs common-law claims. 1. False Arrest To establish a constitutional claim of false arrest, the plaintiff must demonstrate (1) that defendant intended to confine him, (2) that he was conscious of the confinement, (3) that he did not consent to the confinement, and (4) that the confinement was not “otherwise privileged.” Singer v. Fulton County Sheriff, 63 F.3d 110, 118 (2d Cir.1995); see also Weyant v. Okst, 101 F.3d 845, 852 (2d Cir.1996); Corona v. Lunn, 2002 WL 550963, at *5 (S.D.N.Y. Apr. 11, 2002). There is no dispute that plaintiff satisfies the first three elements. The question is whether he can satisfy the last. A showing of probable cause for an arrest provides a complete defense to a claim for false arrest. See, e.g., Weyant, 101 F.3d at 852. In the case of a warrant-less arrest, the seizure is presumptively unlawful, and the defendant bears the burden of demonstrating that he had probable cause to make the arrest. See, e.g., Curry v. City of Syracuse, 316 F.3d 324, 335 (2d Cir.2003); Golden v. City of New York, 418 F.Supp.2d 226, 232 (E.D.N.Y.2006). Probable cause exists when the arresting officer relies upon “knowledge or reasonably trustworthy information of facts and circumstances that are sufficient to warrant a person of reasonable caution in the belief that the person to be arrested has committed or is committing a crime.” Weyant, 101 F.3d at 852; accord, Singer, 63 F.3d at 119. In making this assessment, the court must consider the “ ‘totality of the circumstances.’ ” Bernard v. United States, 25 F.3d 98, 102 (2d Cir.1994) (quoting Illinois v. Gates, 462 U.S. 213, 230, 103 S.Ct. 2317, 76 L.Ed.2d 527 (1983)). Thus, the analysis is highly fact-specific. It “turn[s] on the assessment of probabilities in particular factual contexts — not readily, or even usefully reduced to a neat set of legal rules.” Caldarola v. Calabrese, 298 F.3d 156, 162 (2d Cir.2002) (citing Gates, 462 U.S. at 232, 103 S.Ct. 2317). Of particular relevance, the courts have stressed that, in determining whether an arrest is justified, an officer may not disregard plainly exculpatory evidence. Ker-man v. City of New York, 261 F.3d 229, 241 (2d Cir.2001) (citing Kuehl v. Burtis, 173 F.3d 646, 650 (8th Cir.1999)). Moreover, when there are significant evidentia-ry gaps or uncertainties, the police may not ignore them and simply make an arrest based on obviously spotty and uncorroborated evidence. See, e.g., Oliveira v. Mayer, 23 F.3d 642, 647-48 (2d Cir.1994) (citing BeVier v. Hucal, 806 F.2d 123, 128 (7th Cir.1986) (“A police officer may not close her or his eyes to facts that would help clarify the circumstances of an arrest. Reasonable avenues of investigation must be pursued”)). As one court in this district has noted, in assessing probable-cause questions “Second Circuit case law stresses the importance of investigation and corroboration.” Wu v. City of New York, 934 F.Supp. 581, 587 (S.D.N.Y.1996). If there are genuine disputes as to the facts that would determine the existence of probable cause, then the claim must survive to trial. See, e.g., Douglas v. City of New York, 595 F.Supp.2d 333, 340 (S.D.N.Y.2009). That is the case here, as there are disputed issues of fact that preclude granting defendants’ motion on this claim. As noted, the initial investigation developed a set of fairly consistent eyewitness statements from four club employees suggesting (1) that a group of men had first engaged Cabezas in a brawl in the main hallway, (2) that this fight was stopped by Messrs. Huang and Yee, (3) that Cabezas and the pugilistically inclined patrons all moved to the end of the main hall, in the area of the stairwell leading to a door exiting the club, (4) that the brawl resumed in that location, with Cabezas stabbed there, apparently by a long-haired man in a white shirt who leaped at him, and (5) that Cabezas then staggered back down the main hall, clutching his chest and falling to the floor in the vicinity of Room 9. Moreover, the video tapes from the club were consistent with this scenario, even depicting what appears to have been the stabbing by a long-haired man in a white shirt. The same accounts and tapes indicate that Zhao was not in the vicinity of the stairwell at the time of the stabbing, but rather was engaged in finding and putting on his shoes and then walking down the hallway as Cabezas staggered in the opposite direction and sank to the ground. Further inquiries provided consistent support for this scenario, with several informants reporting that the stabber was a man named Tai Bao. In addition, one man who admitted being present confirmed that he had witnessed Tai Bao attack Cabezas with a knife, and described him in a manner consistent with Yee’s observation of the second brawl with Cabezas. Moreover, other reports implicated a second man, Lin, as involved in the stabbing. In formulating his theory of Zhao’s guilt as the murderer, Milan relied on a small snippet of an unenhanced video tape showing only the top portion of Cabezas’s head and not depicting Zhao’s hand actually touching the victim. Moreover, that theory contradicted the considerable body of evidence amassed by other investigators since the night of the murder. All of this evidence was not only known to various police officials, but was amassed as part of a systematic homicide investigation over a period of years and collected in a homicide case file for reference and use by current and subsequent investigators. Indeed, it is not seriously disputed that Milan and Ng (who was involved in the investigation from the start) knew, and Conlon knew or should have known, the basic conclusions of the other investigators and the basis for those conclusions. It also bears noting that the record does not reflect any effort by Milan either to clarify or resolve the evident conflict between his new theory and the prior fruits of investigative efforts from 2001 to 2005 or to justify simply rejecting the contrary evidence. Under these circumstances it cannot be said, as a matter of law, that the arrest of Zhao for murder was supported by probable cause. Defendants do not appear to quarrel seriously with this conclusion. Rather, in an effort to save their motion, they proffer an alternative theory to justify the arrest. Noting that probable cause may be found for a crime, or crimes, other than the one for which an individual was arrested and charged (Defs.’ Mem. in Supp. of Summ. J. 21-23) (citing, inter alia, Devenpeck v. Alford, 543 U.S. 146, 153-54, 125 S.Ct. 588, 160 L.Ed.2d 537 (2004)), they argue that even if the police did not have probable cause to arrest Zhao for the murder of Cabezas, they had a basis to arrest him for a host of other crimes arising from the group assault on the victim. These crimes include third-degree assault, second-degree harassment, third-degree menacing, disorderly conduct, second-degree reckless endangerment, second-degree riot, and unlawful assembly. (Id. at 21-22). All of these asserted crimes are based upon the assumption that Zhao either attacked Cabezas, assisted others in doing so, or attempted to do so before the stabbing. In pressing this argument, defendants largely ignore the pertinent record, which consists principally of the video tapes. Those tapes show a large number of men in the hallway gathered around Cabezas, some of them seemingly pummeling him or otherwise engaged in efforts to cause him physical harm and other people simply standing or milling about or trying to get closer, either to participate or simply to observe. Zhao apparently appears in the videotape at some point, but defendants offer no indication as to where he appears or what he is doing that would justify a conclusion that he is committing a crime. Indeed, the deposition testimony of the Assistant District Attorney in charge of the case — Richard Reibstein — underscores the obscurity of the effort to derive any conclusion as to criminality from that video tape. (Reibstein Dep. 353-54). In pressing their point, defendants ultimately rely simply on the deposition testimony of Sgt. Conlon that he observed on the videotape what he viewed as an assault by Zhao on Cabezas. (Conlon Dep. 35-36). This unadorned conclusory statement is plainly insufficient to justify summary judgment on the probable-cause question. The test is, as noted, an objective one, and the evidence of the reasonableness of the determination by Sgt. Conlon is not his statement of how he interpreted the videotape — a subjective inquiry — but rather what the videotape itself shows. Since the videotape is, at the very least, ambiguous in that respect and since defendants offer no other evidence as to the role that Zhao actually played (as distinguished from Conlon’s brief and conclusory account of his own mental processes), we cannot say that a trier of fact presented with the film could not conclude that it was too ambiguous to justify a reasonable police officer in concluding that Zhao was likely committing a crime. In sum, summary judgment on the federal false-arrest claim cannot be justified on the current state of the record. 2. Excessive Force Plaintiff asserts a claim of excessive force, alleging that defendants Milan and Ng used physical force and threats of violence and other retribution to extract his signature on a false confession authored by them. Defendants argue that this claim should be dismissed by way of summary judgment because plaintiff suffered, at most, only de minimis injury. (Defs.’ Mem. in Supp. of Summ. J. 25-26). In support of this argument, defendants note that plaintiff testified at his section 50-h hearing that the interrogators’ actions of patting him on the face and pushing his face into the table caused him pain for about an hour, and they further note that there is no record of plaintiff ever seeking medical treatment for any alleged injury. (Id. (citing Zhao Dep. 87-88)). Since defendants’ argument on the excessive-force claim is premised on a Fourth Amendment analysis, we assume for present purposes that the “reasonableness” standard imposed by that amendment applies to an allegedly abusive post-arrest station-house interrogation. See, e.g., Graham v. Connor, 490 U.S. 386, 394-95, 109 S.Ct. 1865, 104 L.Ed.2d 443 (1989); Nimely v. City of New York, 414 F.3d 381, 390 n. 7 (2d Cir.2005). Cf. Albright v. Oliver, 510 U.S. 266, 280-81, 114 S.Ct. 807, 127 L.Ed.2d 114 (1994) (Ginsburg, J., concurring) (Fourth Amendment applies from time of arrest to initiation of criminal proceedings). In applying this test, the trier of fact must look to whether, in light of the circumstances confronting the officer, the amount and nature of the force used was “objectively reasonable.” Graham, 490 U.S. at 397, 109 S.Ct. 1865; Mickle v. Morin, 297 F.3d 114, 120 (2d Cir.2002). As emphasized by the Supreme Court, “[determining whether the force used to effect a particular seizure is reasonable under the Fourth Amendment requires a careful balancing of the nature and quality of the intrusion on the individual’s Fourth Amendment interests against the countervailing governmental interests at stake.” Graham, 490 U.S. at 396, 109 S.Ct. 1865 (citations omitted); accord, e.g., Lennon v. Miller, 66 F.3d 416, 425 (2d Cir.1995). The analysis requires “consideration of the specific facts in each case, including the severity of the crime at issue, whether the suspect posed an immediate threat to the safety of others and whether he is actively resisting arrest.” Sullivan v. Gagnier, 225 F.3d 161, 165 (2d Cir.2000). “If the force used was unreasonable and excessive, the plaintiff may recover even if the injuries inflicted were not permanent or severe.” Robison v. Via, 821 F.2d 913, 924 (2d Cir.1987); see also Maxwell v. City of New York, 380 F.3d 106, 108-10 (2d Cir.2004). The evidence provided by plaintiffs deposition and 50-h testimony satisfies the pertinent constitutional standard for an allegation of excessive force, at least for purposes of summary judgment. See Graham, 490 U.S. at 397, 109 S.Ct. 1865. The record offers not the slightest justification for the use of any force against Zhao during his interrogation. He was in custody, surrounded by at least two police detectives, and located within two presumably highly secure police precincts. In addition, and most crucially, there is no indication that at any point he offered or threatened any physical resistance or was in any other way uncooperative with the police except insofar as he initially declined to admit his guilt for a crime that he insisted he had not committed. It necessarily follows that if we credit his testimony on the point — as we must for present purposes— the force used against him was unreasonable. In seeking summary judgment on this claim, defendants argue one point only, that Zhao did not suffer a sufficiently serious injury to qualify for relief on such a claim. Citing a number of district court decisions, they say that his testimony reflects only a “de minimis ” effect from the alleged unjustified force and that the absence of more serious injury precludes liability. (Defs.’ Mem. in Supp. of Summ. J. 26). We disagree. A number of courts have indicated that a claim of excessive force in effectuating an arrest must be supported by some evidence of injury, although they have not specified the precise extent of the required injury or even indicated why the use of completely unjustified force by the police that does not result in physical harm could not yield a constitutional claim for which the appropriate relief would be nominal damages. See, e.g., Williams v. City of New York, 2007 WL 2214390, at *11 & n. 175 (S.D.N.Y. July 26, 2007) (citing cases). Compare Espada v. Schneider, 522 F.Supp.2d 544, 555-56 & n. 12 (S.D.N.Y.2007) (indicating that excessive-force claim under Fourth Amendment can yield nominal-damages award). This line of cases has largely rested on the courts’ assumption that plaintiff must prove some adverse physical effect, some even requiring long-term injury or medical treatment. See, e.g., Washpon v. Parr, 561 F.Supp.2d 394, 406-07 (S.D.N.Y.2008); Rincon v. City of New York, 2005 WL 646080, at *5 (S.D.N.Y Mar. 21, 2005). We respectfully disagree with those courts that have at least impliedly imposed a requirement for documented or long-term injuries in such circumstances as a predicate to liability. In doing so, we note that the extent and nature of the injury, if any, is typically relevant in an arrest context not merely on the question of the amount of damages, but also because it is probative of the amount and type of force actually used by the arresting officers, and that in turn is likely to reflect on the reasonableness of that force, though reasonableness of course turns as well on the circumstances of the arrest, including— most notably — whether and to what extent the arrestee offered any resistance. It also bears emphasis that an arrest is by nature an act involving some degree of dominion, and hence force, that the police must exercise over the arrestee, and thus it makes some sense to require a showing of some minimum amount of injury as a marker of a more-than-nominal use of force, in order to trigger a Fourth Amendment inquiry. Even in the arrest context, however, the Second circuit has indicated that a very minimal injury is sufficient to trigger potential liability. Thus, for example, in Robison the plaintiff testified that an officer had pulled her out of her car, yanking and twisting her arm, and had thrown her against the vehicle. Her only injury was a bruise of unspecified extent and degree, with no indication that it persisted or required any medical treatment. Nonetheless the Court of Appeals held this showing sufficient for plaintiffs Fourth Amendment excessive-force claim to survive summary judgment. 821 F.2d at 923-24; see Mickle v. Morin, 297 F.3d 114, 120-21 (2d Cir.2002) (citing cases) (reversing judgment as a matter of law when plaintiff alleged injury from the use of handcuffs that were assertedly too tight); Davis v. City of New York, 2007 WL 755190, at *12-13 (E.D.N.Y. Feb. 15, 2007) (denying summary judgment when plaintiff alleged redness and soreness in shoulder after officer kicked her); see also Blair v. City of New York, 2009 WL 959547, at *10-11 (E.D.N.Y. Mar. 31, 2009) (rejecting need to show continuing or long-term injury or medical treatment). In this case, as noted, the alleged excessive force did not occur at the time of the arrest. Rather, it took place while plaintiff was being questioned at two precincts, and the record reflects no reason for any use of force at that stage. In such circumstances any force is potentially illegitimate — again depending on the circumstances — and hence the notion that the injury must be more than “de minimis ” to trigger an assessment of a Fourth Amendment claim appears unjustified. Even if we exclude arguendo the possibility of a nominal damage award, we do not believe that any particular quantum of physical injury is required in such circumstances, since the evidence demonstrates that no use of force was justified. That is the scenario here, which involved an interrogation of an unresisting previously-arrested individual. In any event, the record here is sufficient to deny summary judgment. The plaintiff testified that, apart from having “patted” his face, Det. Ng pressed his head down against the table for some unspecified period of time and with some unspecified degree of force. Zhao further testified that this left him in pain for about an hour. Such transient pain should suffice for the claim to survive summary judgment. 3. The Monell Claims Plaintiff seeks to hold the City liable for the constitutional torts of the individual police defendants. Defendants have moved for summary judgment on this set of claims, arguing that plaintiff cannot prove municipal responsibility for any such wrongful conduct. To establish the City’s liability on these claims, plaintiff must show that the City bore some responsibility for violations of his constitutional rights. See, e.g., City of Canton v. Harris, 489 U.S. 378, 385, 109 S.Ct. 1197, 103 L.Ed.2d 412 (1989) (“[A] municipality can be found liable under section 1983 only where the municipality itself causes the constitutional violation at issue.”) (emphasis in original). To do so, he must demonstrate both a constitutional violation and a sufficient causal relationship between the violation and a municipal policy or practice. Monell v. Dep’t of Soc. Servs., 436 U.S. 658, 694, 98 S.Ct. 2018, 56 L.Ed.2d 611 (1978); Batista v. Rodriguez, 702 F.2d 393, 397 (2d Cir.1983). Plaintiff may demonstrate the existence of a policy or practice in a variety of ways. First, he may provide evidence of a formal policy officially adopted by the municipality. Monell, 436 U.S. at 690, 98 S.Ct. 2018. Second, a single unconstitutional act or decision, when taken by an authorized decision-maker, may be considered policy and thus subject a municipality to liability. Bd. of County Comm’rs of Bryan County v. Brown, 520 U.S. 397, 405-06, 117 S.Ct. 1382, 137 L.Ed.2d 626 (1997); see generally Pembaur v. City of Cincinnati 475 U.S. 469, 481-84, 106 S.Ct. 1292, 89 L.Ed.2d 452 (1986). Third, a policy may be established by showing that the acts of the municipal agent were part of a widespread practice that, although not expressly authorized, constitutes a custom or usage of which a supervising policy-maker must have been aware. See City of St. Louis v. Praprotnik, 485 U.S. 112, 127, 108 S.Ct. 915, 99 L.Ed.2d 107 (1988); Monell, 436 U.S. at 690-91, 98 S.Ct. 2018. Fourth, where a municipality’s failure to provide adequate training or supervision of its agents rises to the level of deliberate indifference, section 1983 liability may lie against the municipality. See, e.g., Brown, 520 U.S. at 407-08, 117 S.Ct. 1382; see generally City of Canton, 489 U.S. at 388-89, 109 S.Ct. 1197. Finally, we note that “a single incident alleged in a complaint, especially if it involved only actors below the policy-making level, does not suffice to show a municipal policy.” DeCarlo v. Fry, 141 F.3d 56, 61 (2d Cir.1998) (quoting Ricciuti v. New York City Transit Auth., 941 F.2d 119, 123 (2d Cir.1991)). The first step in a Monell analysis is to determine whether agents of the City have violated the plaintiffs constitutional rights. If so, the question remains as to the role, if any, of City policy or practice in bringing about those illegal acts. See, e.g., Amnesty Am. v. Town of W. Hartford, 361 F.3d 113, 124-31 (2d Cir.2004) (analyzing first whether plaintiffs had shown a violation of their constitutional rights and then analyzing plaintiffs’ theories of municipal liability). For reasons already noted, we conclude that there are at least triable issues of fact regarding the viability of plaintiffs claims for false arrest and excessive force, and we further note that defendants have not challenged the triable status of plaintiffs claims for malicious prosecution and self-incrimination. Hence the remaining question is whether plaintiff has proffered sufficient evidence to permit a trier of fact to find that the City bore some legal responsibility for those alleged violations of his rights. In the course of briefing the current motion, plaintiff has limited his theory of Monell liability principally to the contentions that the City failed adequately to train the officers in a variety of respects, including permissible techniques of interrogation and evaluation of evidence, and also failed adequately to supervise and discipline officers inclined to make merit less arrests or to engage in physically abusive behavior with suspects. Defendants contend that plaintiff cannot prevail on these contentions. We agree. (a) Failure to Train To impose liability on a municipality for a failure to train its police officers, a plaintiff must establish not only that his rights were violated and that the violation is attributable to the training failure, but that the City, in failing to adequately train the police, acted with at least deliberate indifference to the rights of the public. See, e.g., City of Canton, 489 U.S. at 388-89, 109 S.Ct. 1197. To meet this demanding standard, see, e.g., id. at 391-92, 109 S.Ct. 1197, the plaintiff must demonstrate that the relevant policy-maker knew “to a moral certainty” (1) that the police will confront a given set of circumstances that present the officers with a difficult decision, (2) that adequate training would make that decision easier and more reliable or that there is a history of bad choices having been made in that situation, and (3) that the wrong choice in such circumstances will frequently trigger a violation of the constitutional rights of a member of the public. See, e.g., Jenkins v. City of New York, 478 F.3d 76, 94 (2d Cir.2007); Green v. City of New York, 465 F.3d 65, 81 (2d Cir.2006). Moreover, the plaintiff must also “identify a specific deficiency in the city’s training program and establish that that deficiency is closely related to the ultimate injury, [that is,] that it actually caused the constitutional deprivation.” Jenkins, 478 F.3d at 94 (citing Green v. City of New York, 465 F.3d 65, 81 (2d Cir.2006)). Plaintiffs showing manifestly fails to create a triable issue with regard to most of these elements. In attacking the Police Department training program, he contends that the individual defendants received insufficient training time on custodial interrogations, that the training materials do not tell the officers when to accept the claims of an arrestee that he is innocent and when to terminate the interrogation, that the materials do not advise against “impermissible promises,” and that the materials do not offer guidance in detecting false confessions of guilt or minimizing the risk of false confessions. He further criticizes one passage in a training manual that suggests that, in administering Miranda warnings, the police say to the suspect, before asking if he is willing to waive his rights, that if he does not agree to talk “you won’t get to tell your side of the story.” .Finally, he also complains about the absence of a City policy mandating the videotaping of all interrogations. (Pl.’s Mem. in Opp’n to Summ. J. 6-13). As a separate matter, plaintiff also contends that the Department does not adequately advise its officers as to the capacities of its in-house Technical Assistance Response Unit. (Id. at 13-15). This omission assertedly explains the failure of the individual defendants to obtain an enhancement of the video footage that ultimately demonstrated that Zhao had not stabbed Cabezas. (Id.). Plaintiff fails to proffer evidence sufficient to demonstrate, or to permit a trier of fact to find, that the Police Department has acted with deliberate indifference in designing its training program or that the omissions that he cites led to the violation of his rights by the individual defendants. Hence, regardless of whether the criticisms of the training program have any merit, his Monell claim does not. Plaintiff offers no evidence that the amount of time devoted in training to custodial interrogations — the exact amount is uncertain since the various individual defendants offered varying time estimates (Milan Dep. 442-43; Ng. Dep. 81) — is self-evidently inadequate, much less that it is inconsistent with supplying the basic guidance needed by the officers, or that the failure to devote more time to this subject by itself makes it more likely that the police will mishandle the questioning of suspects already in custody. He also offers no evidence that the alleged shortness of time devoted to the subject is linked to a pattern of coerced confessions or that it caused the asserted violation of his rights by the individual defendants. Plaintiffs further assertion that the training is deficient in not providing guidance about when to believe a suspect’s denial of guilt and when to stop the questioning is equally devoid of substance. We assume for purposes of discussion that many arrestees, when questioned, deny their guilt, but plaintiff fails to offer any indication of what police officers should be taught in the way of discerning whether those denials are truthful. Presumably the principal way in which criminal investigators ascertain the truth or falsity of claims of innocence is through the use of the full array of investigative techniques to unearth evidence, and plaintiff does not suggest that the training materials are generally deficient in discussing those investigative techniques. If plaintiff is implying that officers should also be given some additional training in psychological assessment of suspects — a point he never makes explicitly — that suggestion is not tantamount to a demonstration of manifest deficiency in training and offers no link whatsoever to a pattern of coercive interrogations caused by police officers’ failure to understand that many suspects’ denials of guilt are credible. The argument equally fails because it offers no evidence that such training in psychology would have altered the conclusion of the individual defendants that Zhao was guilty. As for plaintiffs reference to “impermissible promises,” we take that to refer to a suggestion that the police allegedly made to Zhao that if he confessed, he would receive lenient treatment. (Zhao Dep. 193-94). This argument is baseless. Plaintiff offers no reason to believe that it is inappropriate to mention to a suspect that his cooperation may yield a lesser charge or sentence, and he offers no evidence to suggest that a failure by the Department to prohibit such a comment reflects deliberate indifference to the rights of arrestees or tends to cause false confessions. He also offers no evidence to suggest that the absence of such a reference made to Zhao would have led him not to confess. Plaintiffs case is based on the contention that he consistently denied his guilt and that he was forced to sign a false document by physical violence and threats about his fate and that of his family if he continued to insist on his innocence. Hence, in any event he offers no evidence that his signing the document was linked to an impermissible promise rather than to illegal affirmative behavior by the interrogators — a form of conduct that he never shows was encouraged by Police Department training. As for the Department’s asserted failure to teach its officers how to spot or prevent a false confession, again, plaintiff offers no competent evidence that this is a common problem that requires more specific training. Moreover, and still more important, he utterly fails to show how the absence of such training is linked to the violation of his own rights. As noted, he is not claiming that he chose to make a false confession and that the individual defendants failed to spot its falsity, but rather that they manufactured a false confession and compelled him to sign it. The other training issue that plaintiff raises concerning interrogations involves the way in which Miranda warnings should be administered. He seems to complain that the suggested comment about a suspect’s opportunity to tell his side of the story impermissibly encourages the suspect to waive his right to silence or counsel. Again, plaintiff offers no evidence that there is a pattern of suspects waiving their right to silence because the police make this statement, but still more crucial is his failure to offer any evidence that this is what the defendants told him or that such a statement caused him to waive his Miranda rights. Plaintiff presses two other theories lumped under the training rubric. Both are inadequately supported to survive summary judgment. First, he complains that the Police Department did not adequately train its officers about the capacities of the Department’s TARU unit, including particularly its ability to expand the field of vision of some types of video tape. Whether this be the case or not, plaintiff fails to offer evidence that this omission should have been recognized by the ultimate policy maker to pose a substantial threat of constitutional violations. There is simply no evidence that suspects other than plaintiff have been caught in the toils of the criminal justice system because police officers or officials did not see the potentially accessible edges of videotapes as a result of not knowing that TARU could reveal those margins. Second, plaintiff complains about the refusal of the Police Department to videotape all custodial interrogations. This policy position is certainly a debatable one— indeed, it has drawn much respectable criticism. See, e.g., William A.
