The FBI and U.S. Justice Department have acknowledged that almost all of the experts in a forensic unit dedicated to microscopic hair comparison gave flawed testimony against defendants before 2000, the Washington Post said.
The National Association of Criminal Defense Lawyers and the Innocence Project found that 26 of the 28 examiners in the FBI's microscopic hair comparison unit overstated evidence in more than 95 percent of 268 trials that the groups have examined so far, the Post said.
