For decades the FBI has been using hair analysis and other forms of DNA testing to aid in the conviction of defendants. The science has certainly helped defendants who are accused of violent crimes, murder and rape to clear their name, too, but the FBI has recently announced that it will be looking into some of its cases to check for faulty science. One of the biggest problems the FBI has had, it seems, is agents making claims about hair analysis that can’t be supported by science. When those statements led to a conviction, it is very possible that the wrong person was convicted.
