FBI overstated forensic hair matches in nearly all criminal trials — for decades.


The Washington Post is out with a report that the FBI’s Forensic experts falsely testified in hundreds of criminal trials that hair samples taken from crime scenes matched hair folicles taken from defendants. In every one of these cases, the FBI was lying, exaggerating or overstating the strength of the alleged hair match. In many cases, the alleged hair matches were the only or the primary evidence linking defendants to a crime. Untold dozens if not hundreds of innocent people have been convicted on the basis of the FBI’s false testimony.
