dprovine (140134) writes "According to a joint investigation by series of articles in The Washington Post and 60 Minutes, a forensic test used by the FBI for decades is known to be invalid. The National Academy of Science issued a report in 2004 that FBI investigators had given "problematic" testimony to juries. The FBI later stopped using "bullet lead analysis", but sent a letter to law enforcement officials saying that they still fully supported the science behind it. Hundreds of criminal defendants — some already convicted in part on the testimony of FBI experts — were not informed about the problems with the evidence used against them in court. Does anyone at the Justice Department even care about what effect this will have on how the public in general (and juries in particular) regards the trustworthiness of FBI testimony?"
