Almost every examiner in the FBI's hair analysis unit repeatedly overhyped evidence to aid prosecutors over a two-decade period ending in 2000, according to The Washington Post. The finding comes from an ongoing review of cases conducted by the National Association of Criminal Defense Lawyers and the Innocence Project in conjunction with the federal government. Per the review, 26 of 28 forensic hair analysts overstated evidence in 95 percent of the 268 trials examined so far. The FBI and Justice Department acknowledged the errors, saying in a statement they were "committed to ensuring that affected defendants are notified of past errors and that justice is done in every instance."
