allow the defense to impeach the credibility of a prosecution witness. Aftermath Brady was given a new hearing, where his sentence was commuted to life imprisonment. Brady was ultimately paroled. He moved to Florida, where he worked as a truck driver, started a family and did not re-offend. Police officers who have been dishonest are sometimes referred to as "Brady cops". Because of the Brady ruling, prosecutors are required to notify defendants and their attorneys whenever a law enforcement official involved in their case has a confirmed record of knowingly lying in an official capacity. This requirement has been understood by lawyers and jurists as requiring prosecutors to maintain lists, known as Brady lists, of police officers who are not credible witnesses and whose involvement in a case undermines a prosecution's integrity. Brady has become not only a matter of defendants' due process trial rights, but also of police officers’ due process employment rights. Officers and their unions have used litigation, legislation, and informal political pressure to push back on Bradys application to their personnel files. This conflict over Bradys application creates a divide between prosecutors and police officers, and between police management and police labor. Brady evidence also includes evidence material to credibility of a non-police witness, such as evidence of false statements by the witness or evidence that a witness was paid to act as an informant. In United States v. Bagley (1985), the Court narrowed the reach of Brady by stating the suppressed evidence had to be "exculpatory" and "material" for a violation to result in the reversal of a conviction. Harry Blackmun wrote in Bagley that "only if there is a reasonable probability that, had the evidence been disclosed to the defense, the result of the proceeding would have been different. A 'reasonable probability' is a probability sufficient to undermine confidence in the outcome." See also List of United States Supreme Court cases, volume 373 Brady material Connick v.
