The Justice Department has admitted almost every member of an FBI unit specializing in forensic hair samples gave exaggerated testimony in nearly every case where they testified against suspects. According to The Washington Post, a review has found 26 out of 28 examiners overstated forensic matches in ways that favored prosecutors in more than 95 percent of trials examined so far. The trials took place over a 20-year period before 2000. They include 32 cases in which prisoners were sentenced to death, including 14 who were executed or died in prison.
