FBI Overstated Forensic Hair Matches In Nearly All Trials Before 2000

schwit1 writes The Justice Department and FBI have formally acknowledged that nearly every examiner in an elite FBI forensic unit gave flawed testimony in almost all trials in which they offered evidence against criminal defendants over more than a two-decade period before 2000. Of 28 examiners with the FBI Laboratory's microscopic hair comparison unit, 26 overstated forensic matches in ways that favored prosecutors in more than 95 percent of the 268 trials reviewed so far, according to the National Association of Criminal Defense Lawyers (NACDL) and the Innocence Project, which are assisting the government with the country's largest post-conviction review of questioned forensic evidence. The cases include those of 32 defendants sentenced to death. Of those, 14 have been executed or died in prison, the groups said under an agreement with the government to release results after the review of the first 200 convictions.

      Lord Acton hit the nail on the head. 128 years ago he wrote that, ""Power tends to corrupt, and absolute power corrupts absolutely". Unfortunately, no one has ever devised a way of running societies without giving power to certain individuals. With a very small number of honourable exceptions (which prove the rule), that power has corrupted them. We see it around us almost every day, and the people who rise to control entire nation states display the corruption due to power in singularly pure and concentrated form.

      The technicians working in the FBI labs had a very limited form of power, but within that particular domain their sway was almost unchallenged. What expert would dispute the word of the mighty FBI, what lawyer would challenge it, what judge or jury would not be impressed by it? And the technicians' bosses had more power, which was assuredly focused on the important task of getting convictions. I rather doubt that any lab technician at the FBI ever got much career advancement out of frequently discrediting prosecution evidence. Every bureaucratic organization measures itself according to a limited set of drastically oversimplified metrics, and conviction rate is an important metric for any law-enforcement organization. The higher up the tree you go, the greater the desire for more convictions, and the less the concern for whether they are justified or not.

    The same thing happened some years back with fingerprint evidence. The people who are responsible for the analysis of forensic evidence should be 'blind', i.e. they should not have access to the context of the case. If they are given two fingerprints to match, they should merely be asked whether or not they are a match, and not told where they come from or even which case they pertain to. Then there would be far less bias. Also, they should not testify in trials, merely issue an affidavit of their results.

It is now obvious that the false positive rate is completely unacceptable.
