On the Dangers and Potential Abuses of DNA Familial Searching

Advocatus Diaboli sends a story of how a high tech forensic procedure almost led investigators to the wrong person. In 1996, a young woman named Angie Dodge was assaulted and murdered in Idaho Falls, Idaho. There was a conviction in the case, but later reports claimed the wrong man was in prison, and police thought there were more than one attacker anyway. This eventually led to the re-opening of the investigation. Using DNA evidence that had been preserved from the crime scene, police used a controversial technique called familial searching to try to find a lead. This method is used when there is no direct DNA match within the available databases. Instead, it tries to identify family members of the suspect. Police found a partial match, which eventually led them to Michael Usry, a New Orleans filmmaker. They convinced a judge to provide a search warrant to extract Usry's DNA and test it against the sample. It wasn't until a month after the extraction that they told him he'd been cleared.

      Your summary may be a bit too brief for the nuances here. It appears that the police found a partial DNA match with the suspect's father (in, remarkably, a privately-maintained - not state-controlled - DNA database), which in turn suggested that a close relative would be match. The police then examined publicly-available genealogy information to identify candidate relatives. From the genealogy records the police narrowed their search to three candidate individuals. Using various other circumstantial information they finally sought a warrant to collect a DNA sample from just one individual.

      There was no concrete evidence, only circumstancial. I find it extremely worrying that he was brought in under false pretenses and that they granted a court order for the DNA sample before any request had been made to him for a voluntary submission.

      Even if someone is your only suspect, he shouldn't be treated as a "prime suspect" without evidence. Usry says in the article that he was worried that they were going to push for charges even when the sample came back negative, and it was the police and FBI's treatment of him that made him worried. It wouldn't have been the first time that an overzealous law enforcement officer had got so fixated on "getting a result" that they would have pushed on, ignoring the evidence.

      The biggest warning light in the article is actually an innocent-looking remark from the Sgt in the case: " “I wish it wasn’t a dead end, but it was.”" I know it's important to solve crimes, but no police officer should ever be disappointed to find out a suspect is innocent. Do you think that one-month wait was lab time? I doubt it. During all that time, some of the officers and agents involved may well have been pushing to continue, on the grounds that he probably passed through the town once, and they think it was a cousin of his, so they would be arguing that he "probably" drove his cousin up and was an accessory.

      There is always the danger with these speculative searches that you end up identifying a suspect then convincing yourself he's the guy, then confirmation bias leads the officers to build a case around lots of selective evidence. In a cold case, you'd be essentially building a "loser edit" for the poor sod you've picked.

Maybe they're even 99% accurate, but that would still mean that there's a 1 in 100 chance that you'll come up as a false positive: enough to worry about I'd say. And if the accuracy isn't even that good... well it makes DNA databases being used for identification a bit worrying. Not so much because they're not useful, but because the police, lawyers, judge, and jury all tend to believe that a match is far more conclusive than it really is. Especially the jury, whose familiarity with DNA evidence comes from daytime television, where it *always* fingers the guilty party.

      You're right. And thats the point. Circumstantial evidence including DNA evidence should never be sufficient to convince us that there is evidence beyond a reasonable doubt. You should need an eyewitness, clear video footage, etc in addition to a DNA match, etc. Simply because someone happens to be at a location at a given time or around that time and made calls to the person murdered, etc. might make them a suspect, but it shouldn't be enough to convict. Nor should DNA evidence alone. With a mere 99.8% accuracy that means that with billions of people on the planet that without additional evidence there will be wrongful convictions if used alone to gain a conviction.

      First off you are crossing back and forth between not liking circumstantial evidence and not liking the accuracy of DNA evidence. Even if DNA evidence was 100% effective, you still have the issue of circumstantial evidence tying them to the actual murder (instead of just to the knife). And if you have eyewitness or clear video footage you may not have to rely on circumstantial evidence, but you do have to deal with the same accuracy problems of DNA. Even the most high resolution video camera probably has far less reliability than DNA. Perhaps they just look like the murderer, just like their DNA could look like the murderer's DNA.

      The problem is not circumstantial evidence or inaccurate evidence. The problem is not enough evidence. Placing the suspect's DNA at the scene may only make you 99.8% guilty, which potentially means about 14 million people on Earth look as guilty as you. But placing you in the same neighborhood during the weekend the murder took place may bring that number down to 20 people. I would be fine with the police questioning all 20 of those people if they couldn't narrow the search more.

      People need to understand that no one has ever been convicted with 100% certainty in the history of history. Perhaps with 99.999999999999999% certainty, but not 100%. Even evidence that is only 2% accurate is useful when combined with a large amount of other evidence (like being in the same neighborhood as the victim, which is probably closer to 0.01% accurate by itself).

      As our society's data crunching abilities grow, we may start to create more quantitative estimates of guilt. We could set a threshold of guilt that has an acceptable amount of false convictions. Say 1 false conviction in 10,000 accurate convictions. Regardless of any delusional ideas that our justice system is set up to never convict innocent people, we will always need to leave room for doubt. That is why we say "beyond a reasonable doubt" instead of "beyond any doubt".

      At the very beginning of any police investigation, police don't - or at least aren't supposed to - start out suspecting anybody at all. They are given (or they collect) information which leads to suspicions: testimony by victims or other witnesses, surveillance video, credit card and phone records, fingerprints, blood or semen at the crime scene.

      In this case, the police found one line of evidence - DNA from semen - that strongly suggested the crime was committed by one member of a family. They then used a number of other, independent types of evidence to narrow down that original list, and eventually to get a warrant to test their single best suspect's DNA. What is your preferred outcome here, that the police ignore the DNA information that they did have? Or that a warrant to test DNA be denied unless the police have already specifically considered and ruled out all seven billion other people on the planet?

    Well, this is one of those questions that has a few big fat "depends" attached to the answer.

    If they were just going to throw away that information, I unqualifiedly agree with you. No reasonable person would refuse to give their DNA if it would be thrown away as soon as it had exonerated them.

    But what if they intend to *keep* that information and use it to match against future crimes? Then a reasonable person might well pause. One obvious uncertainty is what future versions of the government considers a "crime". Even if I have total trust in the "deep state" under President Obama, I should recognize others might reasonably feel differently, and nobody should feel such a level of trust for future administrations yet to be determined.

    Possibly a more serious issue is our assumptions about the perfection of matching DNA samples against vast archives of DNA data. The FBI likes to claim literally astronomical chances like "113 billion to 1" against a false positive DNA match, but they're not exactly disinterested. Furthermore such figures are based on long strings of untested assumptions about things being statistically independent of each other. While it's manifestly clear that false matches are unlikely, we cannot really know whether they are sufficiently likely to treat as positive proof when we're talking about matching against potentially millions of samples.

    So while it's quite reasonable not to be worried about what happens with your biometric data today, it's maybe not so reasonable to be so casual about having it retained and aggregated for decades to come. Keeping data without really testing it's future utility (or even disutility) is something bureaucracies do by habit and instinct, and people with the skepticism and mathematical knowledge to be entrusted with such a decision are few and far between.

    The inclusion of "papers" in the fourth amendment implies the protection of privacy, not just physical possession, and is parallel to DNA. Even before photocopies and data backups, "secure", when applied to "papers", obviously refers to the risk of disclosure of information without the owner's consent more than it does to the loss of that information. After all, truly important papers could have been manually copied and stored separately even in 1776.

    And did you miss the first item on the list: "persons". Our constitution recognizes our bodies themselves and most immediate physical possessions as the first and most important thing the government should respect. Getting the DNA from a database somewhere rather than collecting it from the suspect should make no difference. We should be able to expect our own government to exercise reasonable respect for our privacy and act outside of the wishes of the obvious data owner only after getting a warrant to do so.

    My point is this: how do we *know* the odds against a perfect false match are as high as we think they are?

    I know the way people do these calculations, which is they take p(x1) * p(x2) *... p(xn) as the probability. But note that the validity of this calculation is dependent upon the assumption that the events x1, x2 ... xn are all independent of each other, which if you think about what DNA is is bound not to be true. So I guess you choose x1 ... xn so that they are independent-ish -- that is to say they are correlated to only a negligible degree.

    But how do you know that? Well, you look through some existing databases that is representative enough of the population at large to choose which points of comparison to use.

    "Latent print examiners have long claimed that fingerprint identification is "infallible." 1' The claim is widely believed by the general public, as evidenced by the publicity generated by the Mayfield and Cowans cases, with newspaper headlines like "Despite Its Reputation, Fingerprint Evidence Isn't Really Infallible.' 12 Curiously, the claim even appears to survive exposed cases of error, which would seem to puncture the claim of infallibility.'" Such cases have been known since as early as 1920 and have not disturbed the myth of infallibility.' 4 Today, latent print examiners continue to defend the claim of infallibility, even in the wake of the Mayfield case.' 5 For example, Agent Massey commented in a story on the Mayfield case, "I'll preach fingerprints till I die. They're infallible. 16 Another examiner declared, in a discussion of the Mayfield case, "Fingerprints are absolute and infallible."' 17 http://scholarlycommons.law.no...

    "The rhetoric of infallibility proved helpful in establishing the admissibility of forensic DNA tests and persuading judges and jurors of its epistemic authority.7 It has also played an important role in the promotion of government DNA databases. Innocent people have nothing to fear from databases, promoters claim. Because the tests are infallible, the risk of a false incrimination must necessarily be nil. One indication of the success and influence of the rhetoric of infallibility is that, until quite recently, concerns about false incriminations played almost no role in debates about database expansion. The infallibility of DNA tests has, for most purposes, become an accepted fact-one of the shared assumptions underlying the policy debate.
    In this article, I will argue that this shared assumption is wrong. Although generally quite reliable (particularly in comparison with other forms of evidence often used in criminal trials), DNA tests are not now and have never been infallible. Errors in DNA testing occur regularly. DNA evidence has caused false incriminations and false convictions, and will continue to do so. Although DNA tests incriminate the correct person in the great majority of cases, the risk of false incrimination is high enough to deserve serious consideration in debates about expansion of DNA databases. The risk of false incrimination is borne primarily by individuals whose profiles are included in government databases (and perhaps by their relatives). Because there are racial, ethnic and class disparities in the composition of databases, the risk of false incrimination will fall disproportionately on members of the included groups.8,9" http://www.councilforresponsib...
