FBI Overstated Forensic Hair Matches In Nearly All Trials Before 2000 173

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.

      "One of the many reasons for the bewildering and tragic character of human existence is the fact that social organization is at once necessary and fatal. Men are forever creating such organizations for their own convenience and forever finding themselves the victims of their home-made monsters".

    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.

      That doesn't solve the problem. The FBI can simply fire or transfer elsewhere anyone who doesn't lean towards positive matches. It wouldn't take long for the experts to realise that saying yes a lot is good for their careers, but expressing doubt in court is going to lead to no more court appearances and a demotion to lab tech.

            A hair versus a fingerprint. On average a person has 100,000 hairs on the head and they loose on average 100 every single day, that is 36,500 hairs over a year (have you any idea how long those hairs can lost and how far they could travel, attached to another persons clothing), for which the US legal system in all of it's rampant stupidity now holds you legally liable. Now add to this shitty testing, so basically a scam to enable easy prosecution and early promotions.

      • That issue could be solved by an outside auditing body. They would send in samples that are known to be matches or not matches, and search for a statistically significant deviation in outcomes. Of course, having an auditing body truly unassociated with the FBI/CIA/NSA/Local policing force would solve MOST issues with policing these days, and would ruin some of the nice little fiefdoms people have been spending the last few decades building... which is why it will never happen.

          The only acceptable solution (if you care about justice) is to stop putting so much weight on fingerprint evidence. It's basically worthless. The weight applied to DNA evidence needs to be scaled right back too.

      Even before that, though, we need high-quality, doubly blinded trials to establish how well any of these comparison-based forensic methods actually work. Evidently, a key problem with hair comparison was that no one actually had any idea how reliable it was for "matching" a sample to a suspect. It is now obvious that the false positive rate is completely unacceptable.

      We should have known this long before anyone even thought about using hair comparison evidence at trial, and the sad thing is that the experiments needed to rigorously evaluate this technique aren't even very complicated. For prosecutors, though, it is undoubtedly a lot more fun to impress juries with your scientific-sounding evidence and experts than it is to ask whether the evidence is actually reliable, and you can bet that the hair comparison "experts" were not in any hurry to show that their work was a sham.

        They do things like that for the first one. Once an evidence is on the "approved" list, you aren't allowed to question it. It's considered a waste of the court's time to have someone fighting a speeding ticket call in 10 experts on RADAR to impeach the speed gun, every time someone with enough money gets a speeding ticket. You can question the use that once, but not the underlying tech. It's illegal to question it (your jurisdiction may vary).

      until someone actually saw a YouTube clip of an elk-attack and asked the lab if it could have in fact been an elk. Answer: Yes. Most likely.

After he was put to death, they figured out it was just carpet glue patterns.

      The article is very misleading on several points. It gives the impression that there was a problem "in almost all trials"; that's not what happened.

      Of the ~21000 requests for an analysis, the lab reported a match about ~2500 times. Of those, the evidence was used in something like 268 trials, and a retrospective analysis of the DNA revealed that the hair did indeed match almost 90% of the time.

      The bigger problem (which is where the "almost all") part came from is that when the evidence was actually presented at a trial, the expert witness overstated the reliability of the hair match; if they had stated that the analysis was only 90% accurate there wouldn't have been a problem.

      A retrial in the 27 or 28 cases in which DNA revealed a mismatch is certainly in order. Otherwise there is no problem with the conviction; a retrial would simply replace the hair match with a DNA match anyway.

          Again, misleading does not necessarily mean they knew it to be untrue. They could have bought into the propaganda themselves.

          Agent Smith sets up misleading guidelines setting a particularly low bar for matches on fingerprints, knowing what he's doing could net the wrong people. Agent Jones follows those guidelines and testifies on the assumption that they are sound. Both the court and Agent Jones have been misled, and Jones is not guilty of perjury. Smith did not testify, thus is not guilty of perjury eithe

  • One of the frustrations we slashdotters often suffer is the ordinary person who disbelieves a scientific finding; climate change and anti-vaccers are the most visible at present. Yet it is stories like this that give people every justification for their scepticism; we need to be willing to hear their attitude and its reasons!

      Forensic analysis methods are not scientifically validated in general. AFAIK any forensic evidence is admissible if the the judge decides so. The general standard is that is sounds plausible.

        No. The general standard is the Daubert standard (so named because it arose in Daubert v. Merrell Dow Pharmaceuticals, 509 U.S. 579 (1993). The standard is:
        Judge is gatekeeper: Under Rule 702, the task of "gatekeeping", or assuring that scientific expert testimony truly proceeds from "scientific knowledge", rests on the trial judge.
        Relevance and reliability: This requires the trial judge to ensure that the expert's testimony is "relevant to the tas

    • Science itself does not have a bias, but scientists have bias' and they have vested interests. Who is going to bite the hand that feeds it? It does not mean it is a conscious bias, but as humans we all have bias as such the "expected" result has to be hidden in some sort of double-blind methodology.... For hair -- give them the prime sample and then 10 or 20 samples that have a mix of similar DNA origins (i.e. if it is asian hair - 20 samples of asian hair mixed in with the suspect sample to match to).

      AGW and antivaxxers fly in the face of established science. With hair forensics there was no established science, just an echo chamber of 'experts' under pressures to prove guilt. This is just FBI cases. What about state and other cases based on the same science? What of other "scientific" forensic processes then and now that a jury can't possibly understand. All a jury knows is that a congenial, nicely dressed, "expert" with superior "credentials, certifications, education, and achievements" states th
      • That's the problem we have. Given how much of 'accepted science' gets challenged and reworked, we are always faced with a spectrum from the very secure to the totally crackpot. After all, Einstein successfully torpedoed Newton's laws of motion, which were as widely accepted as you get. Somehow we need to have a process for determining whether a scientific claim is sufficient to justify its use for criminal trials. On a good day the court process will do that; on a bad day a poor quality lawyer will be unwil

    And this, people, is why you don't have the death sentence.
    • by Livius ( 318358 )

      In a way, yes. The practical argument against capital punishment (as opposed to the ethical argument) is that the standard of evidence suitable for such a severe punishment results in capital punishment being more expensive than life imprisonment.

    • by HiThere ( 15173 )

      You are assuming that they care. But what they're probably regretting is that they haven't killed all to ones convicted on fraudulent evidence.

      O, wait, you said "people". You didn't mean officials.

      N.B.: The laws are made and enforced by organizations composed of people who hold power. They *like* holding power. And they are quite willing to kill innocent people to keep it. Some of them would cavail at mass murder.

      I'm not against the death penalty; I'm against making irreparable mistakes.

      There's a way to prevent gung-ho justice: if judgment is later found to be in error, visit the same penalty on those who condemned. Tho I vaguely recall this principle comes from Sharia law, and if so it doesn't seem to limit behavior much in Real Life.

    • This is not a mistake.

      This is presuming that the arresting officers or investigators must have done their job right, so we should support their side of the story.

      The same, effectively, as telling a jury that the defendant must be guilty because why would an innocent man be arrested and in court?
      It's not justice, but so far beyond just covering up mistakes.

        Virginia is still imprisoning an almost certainly innocent man—even after he did the time.

        Of all the maddening stories of wrongful convictions, Michael McAlister’s may be one of the worst. For starters, he has been in prison for 29 years for an attempted rape he almost certainly did not commit. For much of that time, the lead prosecutor who secured his conviction, the origin

    In 2002, the FBI reported that its own DNA testing found that examiners reported false hair matches more than 11 percent of the time.

    As I read the article, the examiners were right 89% of the time and reported a match when there wasn't one 11% of the time. While that is certainly a problem, it's probably at least as accurate as all the other evidence presented at a trial. The best evidence is usually DNA, but people often don't even believe that (e.g. O.J.)

    • That was a supplemental fact from 2002 in a story about stuff encompassing decades. You are missing a lot of information. Did you stop reading at that point?

  • Experts inherently favor the interests of those who pay them. The FBI doesn't get paid to find people innocent. In a world where the FBI can choose to hire this expert or that expert, it will rehire the ones most likely to make a finding helpful to a finding of guilty.

    Courts are masters of deciding truth between opposing parties. Where one side possesses more resources than the other (the U.S. Attorney General's Office vs. the local public defender) the criminal court is crippled to find the truth of guilt
