(Newser) – Prosecutors have failed to notify hundreds of defendants and their attorneys about faulty FBI forensics work that may exonerate them, according to an in-depth Washington Post investigation. The Justice Department spent nine years—from 1996 to 2004—conducting what it calls an "exhaustive" review of 13 agents' forensic work from the 1990s, and found more than 250 questionable cases. But it only revealed that information to prosecutors, and in more than half of those cases, prosecutors kept that information to themselves, the Post discovered. It also found that the DOJ only reviewed the hair and fiber work of one FBI agent, though it was told other examiners' work in that discipline should be questioned.

In one case, prosecutors left a convicted murderer in prison for 12 years after discovering that work leading to his conviction was flawed, before DNA testing finally exonerated him. In another, a man was executed before the DOJ got around to examining his case. The problem with hair analysis, the Post explains, is that there's no consensus on how many common characteristics are needed to "match" two samples. In one case, the Post found that an analyst only matched three—that the hair was black, human, and from an African American—but implied to the jury that he'd used "around 15," and that mistaken matches were "very rare." DNA evidence shows the defendant was almost definitely innocent.

I live in Louisiana. Some 10 years ago Jim Brown was elected our Commissioner of Insurance. Man, he was a good one too. He was cleaning up the insurance "scams" in our state, a number of insurance companies shut down. Insurance companies did not like Jim Brown. When our Governor, Edwin Edwards, finally got caught, the FBI went after Brown too. They charged Brown with "lying to the FBI", which is a federal crime. No voice recording but the FBI agent said in court that he did take notes. Judge denied Browns defense from seeing the notes. Convicted { I believe he was innocent } he served 6 months, enough to make him a felon. Which means he can not run for office again in Louisiana. That was what the insurance companies and the FBI was after. Never, ever answer an FBI agents questions, tell him you will talk to the police or sheriff, but not to him.

Prosecutors measure success in convictions, which has no relationship to justice or getting the right guy. You get a conviction, you succeeded.
