While the Davis case is not ostensibly about snitching, it revolves around some classic dynamics associated with informant use and its unreliability. One recanting witness--Kevin McQueen--was in fact a jailhouse snitch who testified that Davis confessed to him. McQueen had worked several times before as a police informant and knew the value of providing information against other inmates. When Queen recanted, he explained that he had fabricated the confession based on jailhouse gossip and television reports. Here's the excerpt from the original appeals brief:
Ex-inmate Kevin McQueen testified at Davis' trial that Troy had confessed to him. McQueen had been a "snitch" in other prosecutions and his version of Troy's "confession" differed wildly from established facts (e.g. Troy was eating breakfast at the Burger King in the morning). McQueen subsequently admitted, "[t]he truth is that Troy never confessed to me or talked to me about the shooting of the police officer. I made up the confession from information I had heard on TV. and from other inmate's talk about the crimes. Troy did not tell me any of this."This tactic of fabricating other inmates' confessions based on jailhouse talk and publicly available information was made famous by Leslie Vernon White, a Los Angeles jailhouse snitch. In 1989, White went on 60 Minutes and showed reporters how with a few phone calls from the jail he could get enough information to fabricate a confession that police and prosecutors would accept as true. The ensuing Los Angeles Grand Jury Investigation (link to the left) was a response to the White revelations.
Another important aspect of the Davis case that commonly occurs in informant cases is the "first-in-the-door" phenomenon, in which the first suspect to cooperate with police not only gets to direct attention away from himself but can fundamentally shape the official investigation. Red Coles is the man who several witnesses now identify as the real shooter. The day after the shooting, Coles and his attorney went to police and fingered Davis as the shooter--Coles became a witness against Davis at trial. As a result of Coles's cooperation, police resources were directed at Davis. This happens all the time with informants, especially in complex fraud or drug cases--the first suspects to cooperate shape the entire investigation and make it more difficult to discover the truth. Former prosecutor Steven Cohen describes what happens when the government believes a witness who cooperates early:
It is a certainty that the information obtained from the cooperator will become part of the base of information utilized to evaluate future would-be cooperators. Moreover, the information will affect future questioning of witnesses and defendants; it will alter how investigators view the significance of witnesses and particular pieces of evidence; and it may taint the way the case is perceived by the prosecutors and agents. In other words, false information skews the ongoing investigation. The false information may prove critical to issues that have far greater import than whether to accept as true the proffer of another would-be cooperator. Rather, it might impact decisions regarding charges to be filed against other defendants, it might affect decisions related to an appropriate plea for a given defendant, and it might even influence whether the government decides to seek the death penalty.
