OPINION OF THE COURT
BECKER, Chief Judge.
Franklin Wilson was arrested and spent a month in jail for an armed robbery he did not commit. As plaintiff in this civil rights lawsuit arising under 42 U.S.C. § 1983, he claims that his arrest and subsequent incarceration violated his federal and state constitutional rights to be free from arrest and detention without probable cause. The crux of his claim is that the arresting officer, defendant Darrin J. Russo, both lied and omitted material facts during his application for Wilson’s arrest warrant. Russo told the judge that two victims, who each had ample opportunity to view the robber, had stated that the assailant was between 6’3” and 6’5”. Russo did not, however, tell him that Wilson’s driving abstract showed him to be 5’11”. Nor did Russo tell the judge that one of these eyewitnesses did not identify Wilson when shown a photographic array. What he did tell him was that the other victim positively identified Wilson, and that someone else had seen Wilson in the vicinity near the time of the robbery. Wilson urges us to decide that Russo omitted the exculpatory facts with “reckless disregard for the truth” and that the warrant affidavit would not have established probable cause if the officer had been more forthcoming.
The District Court found that Russo had qualified immunity and granted summary judgment in his favor. In evaluating a claim that an officer both asserted and omitted facts with reckless disregard for the truth, we hold that: (1) omissions are made with reckless disregard for the truth when an officer recklessly omits facts that any reasonable person would know that a judge would want to know; and (2) assertions are made with reckless disregard for the truth when an officer has obvious reasons to doubt the truth of what he or she is asserting. Viewing the facts in the light most favorable to the plaintiff, we conclude that Russo acted in reckless disregard for the truth in some, but not all, of his omissions and assertions to the judge. However, since none of these misstatements or omissions were material, in that the warrant would have established probable cause even if Russo had not made them, we conclude that Wilson’s right to be free from arrest without probable cause was not violated. Therefore, we affirm the grant of summary judgment.1
I. Facts and Procedural History
A. The Robbery and Preliminary Investigation
On February 3, 1995, Officers Lipp and Woroniecki of the Franklin Township [784]*784(New Jersey) Police Department responded to a call reporting an armed robbery at the Great Expressions Floral Shop in the Franklin Towne Center. Detective Woro-niecki interviewed Renee Braverman, the owner of the shop, and Graham Druce, an employee in the shop. They both said that the robber was in the store from a little before 3:00 pm until approximately 3:50 pm. When the robber entered the shop, Braverman was discussing’ a bridal order with a customer. Several times during the robber’s visit, Druce approached him and asked him if he needed assistance, which he repeatedly declined. The bridal order customer left around 3:50, and the robber brought a glass vase and candle to the counter, behind which Braverman was standing. The robber asked Druce, who was standing in the back room, if the candle would cause the glass vase to break. When Druce walked towards the counter the robber put his left hand on Druce’s right shoulder and told Braverman to empty the register quickly and put the money in a brown paper bag along with the candle and vase. Druce and Braverman both said they saw a small revolver in his right hand.
Braverman, a white woman who is “around five six,” described the robber as a light skinned black male, approximately 30 years old, “very tall,” between 6’2” and 6’4”, between 190 and 200 pounds, with black wavy hair, a waist-length light denim jacket, cream colored sweater, and blue denim jeans. Druce, a “five-five,five-six” white man, described the robber as a “very tall male, light black in color, his middle 20s, about 25, about 6’5” tall, maybe a little bit taller.” He told the police the robber had an athletic build, was clean shaven, had well groomed short hair and was wearing a blue denim jacket, blue denim jeans, and sneakers. Druce said that if he saw a picture of the robber he was absolutely certain he could pick him out because of his noticeable height.
Detective Bisignio, also of the Franklin Township Police, canvassed the area for witnesses. Kelly N. DaVila, who worked in a nearby dental office, told him that she had seen a dental patient named Franklin Wilson in the Franklin Center, walking away from the Mayfair Foodtown Area towards a pizza shop after 3:00 that day, “probably about a half hour” before the police officers arrived (making her estimated viewing around 3:30). She described Wilson as a 6’0” tall, clean shaven, thin, light-skinned black man with brown hair and brown eyes. She told Bisignio that he had some entanglement with heroin because his dental records indicated that he was seeking methadone treatment.
Bisignio relayed this information to Woroniecki, who conducted a criminal history and Department of Motor Vehicles (DMV) check of Wilson. The criminal history report listed Wilson as being 5T0” and weighing 160 pounds. The DMV record apparently listed him as being 5T1”. Woroniecki received a photograph of Wilson from the Middlesex County Identification Bureau, which he took to the Somerset County Sheriffs Office in order to compile a photographic lineup. The office compiling the photographic array was apparently not aware of the physical descriptions of the witnesses. On the afternoon of February 6, Woroniecki fell ill and ceased all involvement in the investigation of the floral shop robbery.
Detective Russo took over the investigation. On February 6, he was provided with Officer Lipp’s report and the photographic array from the Somerset County Sheriffs Office. Lipp’s report includes a summary of the robbery and a description of the robber that combined the Druce and Braverman physical descriptions. The report identifies the robber as between 6’3” and 6’5”. It does not mention DaVila’s assertion that she saw Wilson. Russo claimed that he did not review any other officer’s notes. He testified that he reviewed and authorized the photographic array without knowing what the witnesses had said about the robber.
[785]*785Russo showed the photographic array to Braverman and Druce individually. He told them each that the robber might not be in the array, and that if they were to identify anyone they must be one hundred percent certain that the person they were identifying was the person who robbed them. Braverman immediately selected Wilson’s photograph as representing the robber. Druce studied the array for about two minutes, indicating no recognition, and finally concluded that he could not say with certainty that he recognized the robber among them.
Russo testified that he does not remember whether he knew Wilson’s 'height and weight when he applied for the warrant. When questioned during deposition about whether he knew Wilson’s actual height and weight, he said “Well, it’d probably be on the driver’s license abstract because I obtained that actually just for his address.” In his response to Russo’s summary judgment motion, Wilson made the uncontro-verted assertion that this information is on the driver’s abstract.
B. The Arrest Warrant Application, Arrest, and Initiation of Suit
Russo met with a prosecutor and reviewed the facts before the two of them sought a search warrant from Superior Court Judge Dilts. Through his responses to the questions of the prosecutor, Russo informed Judge Dilts that two witnesses had described the robber as a light skinned black male “six-three to six-five.” He did not tell him that Wilson’s driver’s abstract stated that he was 5’11”, or that his criminal history report stated that he was 5’10”. Russo also represented that he had created a photographic array “as a result of the physical descriptions.” This is contrary to what the record indicates, which is that those making the photo array had the photograph of Wilson, but were never told of the victims’ descriptions of the robber. He told the judge that the owner of the florist shop unequivocally picked Wilson out of a photo lineup. He did not tell him that the other witness had faded to identify Wilson as the robber when shown the same photo array. Russo stated that an employee of a nearby dentist’s office who recognized Wilson had seen him around three o’clock. He did not inform the judge that she had stated that she saw Wilson around 3:30, by which time the robber was already in the shop.
We also note that Russo answered the prosecutor’s questions as if he had been there himself, suggesting that he had been the primary investigator and interviewer at the scene of the crime. He did not tell the judge that, in the photo array, Wilson looked ethnically different from the others.2 Russo also did not inform the judge that height and weight were not indicated on the photo lineup.
On the basis of Russo’s testimony, Judge Dilts issued a warrant of arrest and to search for evidence. Russo executed the warrant the evening of February 6. Wilson was incarcerated for a month, after which the Somerset Grand Jury refused to indict him. Thereafter, he brought this suit against Russo, Woronieeki, and the Franklin Township Police Department under 42 U.S.C. § 1983, alleging that his Fourth, Fourteenth, and Fifth Amendment rights were violated, as well as his rights under the New Jersey Constitution, and the New Jersey common law. The defendants moved for summary judgment, and the District Court granted the motion.3 Wilson appealed.
[786]*786II. The Right to Be Free of Unlawful Arrest
To recover under 42 U.S.C. § 1983, Wilson must establish that a state actor engaged in conduct that deprived him of “rights, privileges, or immunities” secured by the constitution or laws of the United States. See Kneipp v. Tedder, 95 F.3d 1199, 1204 (3d Cir.1996). Because Russo has fairly raised a qualified immunity defense, Wilson has a further burden. According to the doctrine of qualified immunity, law enforcement officers acting within their professional capacity are generally immune from trial “insofar as their conduct does not violate clearly established statutory or constitutional rights of which a reasonable person would have known.” Wilson v. Layne, 526 U.S. 603, 119 S.Ct. 1692, 1699, 143 L.Ed.2d 818 (1999) (quoting Harlow v. Fitzgerald, 457 U.S. 800, 818, 102 S.Ct. 2727, 73 L.Ed.2d 396 (1982)).
The qualified immunity defense requires that we engage in a two-step analysis. First, we must “determine whether the plaintiff has alleged the deprivation of an actual constitutional right at all.” Conn v. Gabbert, 526 U.S. 286, 119 S.Ct. 1292, 1295, 143 L.Ed.2d 399 (1999). Only if he has should we “proceed to determine whether that right was clearly established at the time of the alleged violation.” Id. Summary judgment is appropriate if no reasonable juror could conclude that Wilson’s clearly established rights were violated. See Orsatti v. New Jersey State Police, 71 F.3d 480, 482 (3d Cir.1995).
This does not mean that the jury determines the contours of the right. Rather, after making a legal determination about the existence of a right, and whether it is clearly established, we determine whether the facts on the record are such that a jury could conclude that the clearly established right was violated. See id. As a methodological matter, we commonly work backwards: We arrange the facts in the light most favorable to the plaintiff, and then determine whether, given precedent, those “facts,” if true, would constitute a deprivation of a right. And then, if necessary, we determine if the right is clearly established. In this case, since we conclude that Wilson has not adduced facts from which a jury could conclude that his constitutional rights were deprived at all, we need not engage in the second inquiry.
Wilson contends that he was arrested without probable cause in violation of his Fourth Amendment right to be free from unreasonable seizure. He acknowledges that he was arrested pursuant to a warrant, but claims that the warrant was not supported by probable cause. However, the statements given to Judge Dilts by Officer Russo clearly establish probable cause: He was told that a robbery had taken place; that the descriptions of the victims were used to compile a photo array; that one of the victims had quickly and positively identified the suspect from the photo array; and that an employee in a nearby establishment had seen Wilson in the vicinity near the time he supposedly entered the flower shop.
In light of these facts, the only way that Wilson can succeed is if he proffers evidence that Russo recklessly disregarded the truth in his warrant application, and that a warrant application based on what Russo should have told the judge would have lacked probable cause. As this recitation suggests, an arrest warrant issued by a magistrate or judge does not, in itself, shelter an officer from liability for false arrest. See Sherwood v. Mulvihill, 113 F.3d 396, 399 (3d Cir.1997). Rather, a plaintiff may succeed in a § 1983 action for false arrest made pursuant to a warrant if the plaintiff shows, by a preponderance of the evidence: (1) that the police officer “knowingly and deliberately, or with a reckless disregard for the truth, made false statements or omissions that create a falsehood in applying for a warrant;” and [787]*787(2) that “such statements or omissions are material, or necessary, to the finding of probable cause.” Id.4
A. Reckless Disregard for the Truth
With these precepts in view, we must first consider whether Wilson adduced sufficient evidence that a reasonable jury could conclude that Russo made statements 'or omissions that he “knew [were] false, or would have known [were] false except for his reckless disregard for the truth.” United States v. Leon, 468 U.S. 897, 923, 104 S.Ct. 3405, 82 L.Ed.2d 677 (1984); cf. Franks v. Delaware, 438 U.S. 154, 98 S.Ct. 2674, 57 L.Ed.2d 667 (1978). In Franks, the Court held that where a defendant showed by the preponderance of the- evidence that a false statement necessary to the finding of probable cause was made “knowingly and intentionally, or with reckless disregard for the truth,” the constitution requires that any evidence derived from the exercise of that warrant had be excluded from a criminal trial. Id. at 155, 98 S.Ct. 2674. But as the Court of Appeals for the District of Columbia Circuit has lamented, “[unfortunately, the Supreme Court in Franks gave no guidance concerning what constitutes a reckless disregard for the truth in fourth amendment cases, except to state that ‘negligence or innocent mistake[is] insufficient' ” United States v. Davis, 617 F.2d 677, 694 (D.C.Cir.1979) (quoting Franks, 438 U.S. at 171, 98 S.Ct. 2674). This case, with its hybrid allegation (Russo purportedly doctored some facts and failed to inform the judge of others) requires us to acknowledge that reckless disregard for the truth means different things when dealing with omissions and assertions, and to explain the different methodologies for dealing with each.
1. Omissions
All storytelling involves an element of selectivity.' We cannot demand that police officers relate the entire history of events leading up to a warrant application with every potentially evocative detail that would interest a novelist or gossip (“... the witness blushed when I mentioned the gun, and blinked six times while studying the photographic array. I noticed his hand crept up to his lips (which were chapped) ... ”). On the other hand, one of the reasons for requiring a neutral magistrate to evaluate probable cause is that an uninterested party is presumably better suited to review and evaluate the facts than an officer pursuing a lead. “The point of the Fourth Amendment, which often is not grasped by zealous officers, is not that it denies law enforcement the support of the usual inferences which reasonable men draw from evidence. Its protection consists in requiring that those inferences be drawn by a neutral and detached magistrate instead of being judged by the officer engaged in the often competitive enterprise of ferreting out crime.” Johnson v. United States, 333 U.S. 10, 13-14, 68 S.Ct. 367, 92 L.Ed. 436 (1948) (cited in Payton v. New York, 445 U.S. 573, 586 n. 24, 100 S.Ct. 1371, 63 L.Ed.2d 639 (1980)). It follows that a police officer cannot make unilateral decisions about the materiality of information, or, after satisfying him or herself that probable cause exists, merely inform the magistrate or judge of inculpatory evidence.
Recognizing the tension between the extreme models that could arise if either of these competing concerns were taken alone — requiring a police officer to tell all, and permitting a police officer to independently determine materiality — we follow the common'sense approach of the Court of Appeals for the Eighth Circuit [788]*788and hold that omissions are made with reckless disregard if an officer withholds a fact in his ken that “[a]ny reasonable person would have known that this was the kind of thing the judge would wish to know.” United States v. Jacobs, 986 F.2d 1231, 1235 (8th Cir.1993). In Jacobs, the court concluded that the officer acted with reckless disregard when he told the magistrate that a drug sniffing dog showed “interest” in the bag of the defendant but failed to inform the magistrate that it had not gone into “alert.” Id. at 1234. “Because of the highly relevant nature of the omitted information,” the court held that “the omission occurred at least with reckless disregard of its effect upon the affidavit.” Id.
Wilson alleges that Russo made the following omissions in his warrant application: (1) he did not tell the judge that although Officer Lipp’s investigative report stated that the robber was between 6’3” and 6’5”, Wilson’s driver’s abstract indicated that he was 5’11”; (2) he did not tell the judge that Druce did not pick Wilson out of an array; (3) he did not tell the judge that in the photo array, Wilson looked ethnically different from the others; and (4) he did not mention that height and weight were not indicated on the photo array.
Applying the test adopted above, we address these contentions in turn. Any reasonable person would know that the significant height differential, and the fact that an eyewitness-victim did not identify Wilson, were “the kind of thing[s] the judge would wish to know.” Jacobs, 986 F.2d at 1235. On the other hand, we do not believe that an officer can be expected to communicate the apparent ethnicity of the victim, or slight variations in appearance on the photographic line-up absent circumstances making these factors more important or prejudicial. Finally, the fact that height and weight were not listed on the photo array is so routine as to be unremarkable to a judge. Although these latter facts could be used for impeachment at trial, a police officer cannot be expected to present a judge with complete background.
2. Assertions
Unlike omissions, assertions can be made with reckless disregard for the truth even if they involve minor details — recklessness is measured not by the relevance of the information, but the demonstration of willingness to affirmatively distort truth. In applying the reckless disregard test to assertions, we have borrowed from the free speech arena and equated reckless disregard for the truth with a “high degree of awareness of [the statements’] probable falsity.” Lippay v. Christos, 996 F.2d 1490, 1501 (3d Cir.1993) (quoting Garrison v. Louisiana, 379 U.S. 64, 74, 85 S.Ct. 209, 13 L.Ed.2d 125 (1964)); see also United States v. Clapp, 46 F.3d 795, 800 (8th Cir.1995) (reckless disregard for the truth is exhibited when expressing that which was not “believed or appropriately accepted” as true). An assertion is made with reckless disregard when “viewing all the evidence, the affiant must have entertained serious doubts as to the truth of his statements or had obvious reasons to doubt the accuracy of the information he reported.” Clapp, 46 F.3d at 801 n. 6.
Applying these tests to this case, Russo had reasons to “doubt the accuracy” of his intimation that he had personally investigated the entire case and interviewed the witnesses after the robbery. More importantly, a jury could conclude that Russo “must have entertained serious doubts about the truth of his statement” that the dental worker had seen Wilson around 3:00, instead of around 3:30. Because he told the judge about DaVila’s identification, Russo must have learned of DaVila’s statement from somewhere; a jury could infer that he learned of it from the transcript of DaVila’s statement or a complete report, either of which would include her statement that she saw Wilson about a half an hour before the police arrived, which would place her sighting at about 3:30. If Russo knew of the time difference, he had [789]*789“obvious reasons to doubt” his assertion to the judge that a witness saw Wilson around 3:00.
As to the other information from the other officers’ reports, Wilson did not adduce any evidence that Russo would have examined these reports as a matter of course or policy, or any evidence from which a jury could infer knowledge of their content. Moreover, there is no evidence that Russo knew that the array was developed from Wilson’s photo alone. Therefore, a jury could not conclude that his representation that the array was made “as a result of the physical descriptions” was made with reckless disregard of the truth.5
B. Materiality
Since there was sufficient evidence of omissions and assertions made knowingly, or with reckless disregard for the truth, we turn to the next step of the reconstructive surgery required by our jurisprudence, and assess whether the statements and omissions made with reckless disregard of the truth were “material, or necessary, to the finding of probable cause.” Sherwood, 113 F.3d at 399.6 To determine the materiality of the misstatements and omissions, we excise the offending inaccuracies and insert the..facts recklessly omitted, and then determine whether or not the “corrected” warrant affidavit would establish probable cause. See id. If it does, the grant of summary judgment should be affirmed, for even if there had not been omissions and misrepresentations in Russo’s presentation to Judge Dilts, Wilson would have been arrested.
Probable cause exists if there is a “fair probability” that the person committed the crime at issue. See Sherwood, 113 F.3d at 401. “Probable cause to arrest exists when the facts and circumstances within the arresting officer’s knowledge are sufficient in themselves to warrant a reasonable person to believe that an offense has been or is being committed by the person to be arrested.” Orsatti, 71 F.3d at 483. A police officer may be liable for civil damages for an arrest if “no rea[790]*790sonable competent officer” would conclude that probable cause exists. Malley v. Briggs, 475 U.S. 335, 341, 106 S.Ct. 1092, 89 L.Ed.2d 271 (1986).
The defendants maintain that a positive identification by a victim is sufficient by itself to establish probable cause that the identified party was the offender. While we agree that a positive identification by a victim witness, without more, would usually be sufficient to establish probable cause, this qualified precept cannot be rendered absolute. Independent exculpatory evidence or substantial evidence of the witness’s own unreliability that is known by the arresting officers could outweigh the identification such that probable cause would not exist. Each case must therefore be examined on its facts.
For example, if two identifying witnesses had told the officer that the robber was 7’, and the officer knew that the person in the photograph was 5’, the positive identification would not be enough. Likewise, an otherwise credible victim identification would not provide probable cause if police officers contemporaneously possessed reliable DNA evidence which determined conclusively that the accused could not have committed the crime. Or, if Druce had, equally firmly, picked another person from the photo array, Braverman’s identification might not have been sufficient for Russo to conclude that Wilson “probably” committed the crime. “An officer contemplating an arrest is not free to disregard plainly exculpatory evidence, even if substantial inculpatory evidence (standing by itself) suggests that probable cause exists.” Kuehl v. Burtis, 173 F.3d 646, 650 (8th Cir.1999).7
The cases that the defendants cite for their argument fall into two basic camps: (1) those in which there was no exculpatory evidence or evidence of witness unreliability, such as United States v. Harris, 956 F.2d 177, 180 (8th Cir.1992); and (2) those in which the court concluded that a positive identification was not fatally undermined by unreliability or exculpatory evidence, such as Sharrar v. Felsing, 128 F.3d 810 (3d Cir.1997) and Lallemand v. University of R.I., 9 F.3d 214 (1st Cir.1993). The first class of cases is inappo-site here. Looking at the second class of [791]*791cases, we find that courts have consistently considered the context of an identification, and have not stated that police can rely on any witness accusation, however unreliable or unbelievable.
For example, in Sharrar we affirmed the principle that “[w]hen a police officer has received a reliable identification by a victim of his or her attacker, the police have probable cause.” 128 F.3d at 818 (emphasis added). We concluded in that case that when the witness initially gave one name, but then identified her husband as her attacker, it was reasonable for the officer to “assess Gannon’s demeanor, find her story credible, and rely on her subsequent identification of her husband as the attacker” in part because it was a domestic violence case. Id. Likewise, in Lallemand, the First Circuit concluded that discrepancies in a victim’s description were “trivial, given their nature” and in light of the positive identification, clearly implying that non-trivial discrepancies, or external evidence powerfully undermining the reliability of the witness’s identification, might translate into a finding that there was no probable cause. 9 F.3d at 217.8 We reject the rule suggested by the defendants and engage in the routine probable cause analysis, weighing the inculpatory evidence against any exculpatory evidence available to the officer.
The strongest inculpatory evidence is clearly the positive identification. Braver-man had considerable opportunity to view the robber at the scene of the crime, and she exhibited a high level of certainty. There were three days between the crime and identification, so while it was not an entirely fresh identification, not so much time had passed as to call into question her recollection. Granted, Braverman’s testimony should be viewed with some skepticism because her identification of Wilson was inherently incompatible with her description of the robber — according to the information available to Russo (Lipp’s report), Braverman (and/or her coworker) originally described the. robber as between 6’3” and 6’5”. Although she did not know it, in identifying Wilson she identified someone much shorter. Both of these identifications cannot be correct. However, this indication of unreliability does not, from the vantage point of the arresting officer, fatally undermine the forceful positive identification. Added to this identification is the fact that DaVila testified that she saw Wilson in the vicinity near the time of the theft.
On the other hand, there are three exculpatory facts that Russo should have mentioned: (1) the robber was originally identified as someone 6’3” to 6’5”, while Wilson is four to seven inches shorter;9 (2) one of the two victim-witness with ample opportunity to view the robber failed to identify Wilson when shown a photo array; and (3) DaVila saw Wilson out in the shopping center when he was supposedly in the flower shop. But these exculpatory facts, when weighed against the inculpatory facts, are not strong enough to undermine [792]*792a finding of probable cause. Thus, we conclude that the District Court correctly found that no reasonable jury could find facts that would lead to the conclusion that Wilson’s “corrected” warrant lacked probable cause. Therefore, we do not have to reach the second prong of the qualified immunity investigation, that is, whether the right was clearly established.
In sum, we conclude that the District Court correctly concluded that Russo did not violate Wilson’s constitutional right to be free of unlawful arrest. Therefore, we affirm the grant of summary judgment on qualified immunity grounds.
III. Continued Incarceration
Wilson contends that even if he was properly arrested in the first instance, he was kept in jail in violation of his rights because Russo learned of exculpatory facts after the arrest which should have motivated him to try to release Wilson. On February 7, Russo interviewed Wilson’s friend George Richardson, who told Russo that Wilson had spent February 3 in his company. He told him that Wilson wore blue jeans, tan work boots, a beige sweatshirt and a brown jacket that day. He said that they had gone to the Towne Center, where Wilson went to get a lemonade at the pizza parlor while Richardson went to the bank. As evidence of his veracity, Richardson gave Russo a bank slip with 8:38 stamped on it. Russo testified that he visited the bank and looked at the films from the bank’s surveillance camera to look for Richardson, but that he could not recall what he saw and could not recall if the employees remembered Richardson.10
Wilson contends that Russo’s post-arrest interview with Richardson provided exculpatory information that dissipated probable cause, and that Russo had a constitutional duty to inform the prosecutor of the interview and attempt to get Wilson released. The law in this area is not entirely settled. Compare Brady v. Dill, 187 F.3d 104, 112 (1st Cir.1999) (concluding that police officers generally have no duty to try to release suspects when exculpatory information comes into their possession after a lawful arrest), with id. at 117-125 (Pollak, J., concurring) (proposing a rule by which “[a]n affirmative duty to release arises ... if an arresting or custodial officer ascertains beyond a reasonable doubt that the suspicion (probable cause) which forms the basis for the privilege of arrest is unfounded.”). See also Sanders v. English, 950 F.2d 1152, 1162 (5th Cir.1992) (“[F]ailure to disclose ... undeniably credible and patently exculpatory evidence to the prosecuting attorney’s office plainly exposes[defendant police officer] to liability under § 1983.”); BeVier v. Hucal, 806 F.2d 123, 128 (7th Cir.1986) (“The continuation of even a lawful arrest violates the Fourth Amendment when the police discover additional facts dissipating their earlier probable cause.”).
We do not, today, need to decide these difficult issues. Regardless of the existence and scope of an officer’s duty to seek to release a suspect when probable cause no longer exists, or the level of knowledge that he or she must have in order to trigger that duty, the interview with Richardson clearly did not dispel the earlier probable cause.11 A friend of Wilson gave [793]*793Wilson a partial alibi, and his description of Wilson’s clothing did not match the victims’ descriptions, but he placed Wilson in the vicinity at the time of the robbery, and nothing he said overwhelmed the fact of Braverman’s positive identification. In short, no reasonable jury could conclude that this evidence dispelled probable cause.
For the foregoing reasons, the grant of summary judgment will be affirmed as to the federal claims. The case will be remanded to the District Court for consideration of the state claims.
