Nearly every criminal case reviewed by the FBI and the Justice Department as part of a massive investigation started in 2012 of problems at the FBI lab has included flawed forensic testimony from the agency, government officials said.

The findings troubled the bureau so it stopped the review of convictions last August. Case reviews resumed this month at the order of the Justice Department, the officials said.

The inquiry includes 2,600 convictions and 45 death-row cases from the 1980s and 1990s in which the FBI's hair and fiber unit reported a match to a crime-scene sample before DNA testing of hair became common. The FBI had reviewed about 160 cases before it stopped, officials said.

        That's what I'm implying, yes. Though for the label "crime" to have any actual effect, a prosecutor would have to purse the offense. What prosecutor would press charges against the foresnic laboratory workers who have been so helpful in producing the evidence they've been asked for? Paid for, in fact -- forensic laboratories are funded by the prosecutor's office, which is a glaring conflict of interest for the laboratories.

          This story isn't about intentional fraud by forensic lab workers, much as you seem to want it made into that.

          Its about junk science, that can make even honest lab workers totally wrong.

          “These recent developments remind us of the profound questions about the validity of many forensic techniques that have been used over the course of many decades and underscore the need for continuing attention at every level to ensuring the scientific validity and accuracy of the forensic science that is used every day in our criminal justice system,†Bromwich said.

          The most well publicized of these techniques that was summarily thrown out as total junk science was bullet lead composition matching, which was used to "prove" that the bullet that killed the guy came out of the same box in the possession of the accused.

          It was total bunk, and the bullet could match 10000 boxes of ammunition. But the lab tech didn't do this maliciously, or even knowingly. The manual said you analyse the sample this way and report the results in this fashion. But even junk science done correctly is still junk science.

          Some flunky lab tech at the FBI usually has no ax to grind for some local shooting. But when the science is junk, the results will be too.

            The lab itself might well have blinded itself. It is the prosecutors and courts guilty of fraud.

            As soon as the courts and prosecutors learned (or should have learned) that the qvidence used in uncountable convictions was entirely untrustworthy, they should have called for a re-examination case by case. The fact that they didn't is where criminal fraud comes in. They have willingly embraced the known bad evidence.

        It may be evidence, but it isn't necessarily reliable evidence.
        Ballistics Evidence Under Fire: http://www.americanbar.org/content/dam/aba/publications/criminal_justice_magazine/cjw11scientificevidence.authcheckdam.pdf [americanbar.org]

        The court wrote that "O'Shea [the expert] declared that this match could be made 'to the exclusion of every other firearm in the world.'. . . That conclusion, needless to say, is extraordinary, particularly given O'Shea's data and methods."

        Although the expert had seven years of experience in the field, he was not certified, and his laboratory was not accredited. Moreover, he had never taken a neutral proficiency examination. Finally, he could not cite any reliable error rates. The expert "conceded, over and over again, that he relied mainly on his subjective judgment. There were no reference materials of any specificity, no national or even local database on which he relied. And although he relied on his past experience with these weapons, he had no notes or pictures memorializing his past observations."

        -------

        In 2008, the National Academy of Sciences published a report on computer imaging of bullets. (National Research Council, Ballistic Imaging (2008).) Although firearms identification was not the primary focus of the investigation, a section of the report commented on this subject. After surveying the literature on the uniqueness, reproducibility, and permanence of individual characteristics, the report noted that "[m]ost of these studies are limited in scale and have been conducted by firearms examiners (and examiners in training) in state and local law enforcement laboratories as adjuncts to their regular casework." (Id. at 70.) The report concluded: "The validity of the fundamental assumptions of uniqueness and reproducibility of firearms-related toolmarks has not yet been fully demonstrated." (Id. at 81.)

        ------

        Agreeing with its 2008 Ballistics Imaging report, in 2009 the National Academy of Sciences report on forensic science summarized the state of the research as follows: Because not enough is known about the variabilities among individual tools and guns, we are not able to specify how many points of similarity are necessary for a given level of confidence in the result. Sufficient studies have not been done to understand the reliability and repeatability of the methods. The committee agrees that class characteristics are helpful in narrowing the pool of tools that may have left a distinctive mark. Individual patterns from manufacture or from wear might, in some cases, be distinctive enough to suggest one particular source, but additional studies should be performed to make the process of individualization more precise and repeatable.

      > Almost everything except DNA evidence is unreliable

      Even DNA evidence is not 100%. Part of the problem is that a standard forensic DNA comparison only looks at a small number of loci (at most 13).

      DNA can be damaged during handling, collection or when it is left at the scene, this can reduce the number of testable loci.
      DNA can be contaminated - like when the victim and the perpetrator's blood are mixed in the sample.
      Family members share a lot of common DNA, even completely random strangers typically share 2 or 3 loci.
      For "cold hits" - when you have a sample and want to figure out who it is, the larger the database you are searching against, the more likely a false hit.

      Here are some examples of forensic DNA failures. [nasams.org]

      In essence, DNA is pretty good for ruling people out. It is much less reliable as a tool for proving guilt and the FBI knows this because they have started to forbid defense teams and academics from getting access to their database. [washingtonmonthly.com]

        Any defense lawyer will say that DNA evidence is unreliable. If your DNA is on anything, it doesn't prove that you was anywhere at any particular time. And it may only indicate cross-contamination at the crime scene or at the lab.

        As I understand, DNA "matches" are done with enzymes and, due to the birthday paradox [wikipedia.org], two people in a busy courtroom could be matches.

        There's also the sensitivity of tests. For example, you may be carrying banknotes which have detectable amounts of cocaine but that doesn't mean you're a drug dealer or that you snort coke.

          No. With a correctly administered test (full 13 loci, no sample contamination) the chance of a positive match for two totally random strangers is 1 in trillions -- so even with a database of millions of samples you would still be looking at a 1-in-a-million chance of a false positive. The problems come when those conditions are not met but the test is used anyway.

            Rubbish.
            Assuming equal probability of alleles, if there are two possibilities at each of 13 loci the odds of a match between two samples is 1 in 8192.
            If the alleles don't have equal probability, (they don't) then that can raise or lower the odds of a match.

            (Note for the gp post, as one of the the samples is pre-selected the birthday paradox does not apply.)

              Nearly everything you wrote is wrong.

              Because the 13 loci that are currently used for discrimination are independently assorted (having a certain number of repeats at one locus does not change the likelihood of having any number of repeats at any other locus), the product rule for probabilities can be applied. This means that if someone has the DNA type of ABC, where the three loci were independent, we can say that the probability of having that DNA type is the probability of having type A times the probability of having type B times the probability of having type C. This results in the ability to generate match probabilities of at least 1 in a quintillion (1x1018).

      It took me a long time to figure why people act like this - hide institutional problems rather than fix them. My best understanding is that they have a belief/faith in the "institution" and think that revealing the problems will damage all the good stuff that the institution has done.

      In criminal cases the adversarial system exacerbates that phenomenon because the system encourages people to keep score based on the number of convictions not total amount of justice. Thus information like this puts convictions at risk and even false convictions count as "wins" so double whammy -- the institution is damaged and the careers of people who relied on the corrupt evidence, through no fault of their own, are also damaged. Add in the common belief that if these people aren't guilty of this crime that they are probably still guilty of some crime and there is even more motivation to sweep it under the rug.

      Obviously hiding this stuff ends up making the damage even worse when it eventually does get revealed. But people are notoriously short-term thinkers, many believe that if they hide it good enough it will never come out (and in some cases that is probably true).

      That choice told you the FBI would happily put innocent people in jail as long as they can get the credit for "solving" their investigation, and the FBI have no real interest in finding the actual criminal at all.

      They have the same incentive as a treasure hunter selling the treasures he found. As long as he have enough "proof" to convince one sucker to buy, he has no interest in the real truth. If a test is going to show his "treasure" is a fake, of course he is going to stop doing that test!
