While we may never know what actually happened between DEA Agent Lee Lucas and his informant Jerrell Bray–a hazardous partnership that rocked Cleveland for the last few years– their story reveals the many dangers that arise when law enforcement hitches its wagon to criminal snitches. In 2007, the Cleveland Plain Dealer began extensive reporting on allegations that Bray, a convicted killer and drug dealer, was using his relationship to the DEA to frame rivals and innocent people and that Agent Lucas had lied to make cases. Eventually, over a dozen convictions were reversed, including those of people who pleaded guilty. Story here. Bray was convicted of perjury and is currently serving 14 years; Agent Lucas was prosecuted for perjury and obstruction of justice. Last month, a jury acquitted Agent Lucas of all 18 charges.

Law enforcement agents are rarely prosecuted for relying on bad informants, so the Plain Dealer’s coverage offers a rare glimpse into the ways that an informant can shape–or deform–official decisions.
