Bioethics Group Raises DNA Database Concerns 150

PieGuy107 writes "In its report, The Forensic Use of DNA and Fingerprints: Ethical Issues, the council recommends that police should only be allowed to permanently store bio-information from people who are convicted of a crime. Today, the police of England and Wales have wider sampling powers than the police force of any other country, and the UK has (proportionally, per head of population) the largest forensic database in the world. When the police first began using DNA, consent was required before samples could be taken. A succession of Acts of Parliament and legislative amendments has increased police powers of sampling; the police can now take DNA samples from all persons arrested, without their consent, for recordable offenses (an "arbitrary" classification), and retain the samples indefinitely regardless of whether the person arrested is subsequently convicted or even charged. In response to comments from the Home Office that retaining the DNA of people who were innocent at the time of arrest had helped to solve crimes they committed years later, the Nuffield Council stuck to its guns. "There has to be a limit to police powers," said Dr Carole McCartney, one of the report's authors. "DNA shouldn't be retained simply on the basis that it might turn out to be useful." She added that many of the statistics from the Home Office were "inconsistent, incomplete and confusing" and that much of its evidence consisted of anecdotal accounts of "horrible men caught with DNA"."

Frex, the standard DNA-ID profile for dogs presently only looks at 20 pairs of markers (recently upped from the previous standard of 13 pairs of markers).

      It depends on how they analyze the DNA, if they use a 13 marker system then if at least 7 of them match then you are likely to be related and vice versa, so really even if they do arrest your cousin, they likely only have half the picture unless they do a full analysis of the DNA, in which case if the DNA matches your cousin, they'll know more than enough to exclude you because of the various genetic recombination/crossover that goes on when the two gametes fused that later developed into you.

        • Although specific genes were not what was considered, the issue has arose in the past. Basically, if they found suck a gene (IMO, no such thing exists, and anyone who does think it does exist is a poor geneticist and a worse sociologist) they might call for compulsory sterilization [wikipedia.org], like they did in the past. From www.eugenicsarchive.org

          Eugenicists claimed that criminal behavior was a result of defective genes. Most eugenicists adhered to the prevailing social theory of the early decades of the twentieth century that "culture does not make the man, but man makes the culture," meaning that poor people gravitate toward and contribute to a poverty-stricken environment, and thus create their own degenerate conditions. Thus, while not denying that poor social and cultural background might contribute to criminality, eugenicists argued that criminality, like many other social traits, was ultimately biological in origin.

          Eugenicists were concerned with the noticeable rise in crime rates, especially in the fast-developing urban areas of the United States. They conducted both family pedigree studies and surveys by ethnic and national origin to show that criminality ran high in certain families and groups. Cyril Burt's pedigree analyses in England (on delinquency) supported eugenicists' views that if a trait ran in families it must be genetic. Similarly, Harry H. Laughlin gathered data on incarceration rates by country of origin to show that immigrants to the U.S. from eastern and southern Europe and the Mediterranean countries were disproportionately represented in prisons than "old stock" Americans or recent immigrants from Germany and other Nordic or Anglo-Saxon countries. Laughlin's data had such serious statistical problems that, according to a critique at the time, totally invalidated the conclusions. However, these data formed a cornerstone of the argument Laughlin made to the House Committee on Immigration and Naturalization to curb immigration from Southern and eastern Europe and the Mediterranan. They were also highly influential in eugenicists' lobbying efforts for sterilization laws that would prevent incarcerated criminals from giving birth to "criminal" offspring. If the number of criminals could be reduced through these biological measures eugenicists argued, it would save the state millions of dollars a year.

          And they did, too, see Bell v Buck [answers.com]. Hey, who knows rights people will piss on 'because of genetics' in the future.

    I'd say the standard should be the same as all evidence. Are they allowed to keep your mug-shot forever (yes, as far as I know). If they take a handwriting sample and you are not convicted, are they allowed to keep that? The standard should be the same for DNA. They certainly get to keep your fingerprints right?

    If they request and get it during the course of an investigation I think they should get to keep it. I see no reason why they shouldn't.

    If they start abusing this (arresting people on provably fake charges and such) just to get DNA, they you can do a civil suit. The judge will make 'em toss it and the millions they'll have to shell out every time will help keep them honest.

    But if you are at a murder scene and have knife scratches on you, the police should get to keep your DNA if they use it to rule you in or out, just like they get to keep pictures of you.

    Now if you want to make it so they can keep the DNA but it can't be admitted to court (so they couldn't convict you on that alone) then I would be fine with that. That's probably a good idea, in fact.

      The problem comes about because the police don't have a clue.

      Consider the scenario. You are arrested for a crime you didn't commit. Fortunately, despite the police trying to pin it on you, the real culprit confesses and you are released without a stain on your character.

      Then a little while later you are arrested again because your fingerprints (which were only stored because you were incorrectly arrested before) are found on some recovered stolen mail. The only problem being that you were the _VICTIM_ of the theft. Yes! Your fingerprints were on the mail because you _POSTED_ it!

      No attempt by the police to investigate. Finger print match. Call the person in to the station. Arrest them immediately. And then tell them to accept a caution to get it over with!

Since it probably happens all the time, I'd settle for a monthly email notifying me of the total number of reads/writes/transmissions, with the URL of my transaction history. The history should be sortable by at least agency, case ID, type of record, and time. And of course the records should be confidential, and never sharable to private contractors without my explicit permission, even for gover

      And what if there are no suspects?
      what if you have this piece of DNA that you strongly suspect is the culprits, but since you only have the DNA of convicted crimials, your not going to be able to find anything..

      Also if your against a national DNA database, then your probably of the opinion that DNA is a personal thing, and can only be collected with your consent. How many criminals are going to consent to giving DNA if they think that will help them solve their crime.

    Will they be able to keep track of where you are? No
    Will they be able to know what you've done? No (unless you have actually been involved in a crime)
    Can the information of your DNA be used to harm you? Not if its used ONLY for DNA matching against crime scenes, and kept strictly confidential

    Its not like their monitoring your private life, its simply a recording of your DNA sequence that can only be used in matching to DNA found at crime scenes.

  • Genetic Disposition (Score:3, Interesting)

    What happens if they starting looking at the list of people who commit crimes and compare their DNA looking for links to "genetic disposition" to create a certain type of crime?


    If they example the DNA of thousands of rapists, for example, and find they all have certain genetic traits in common, will they then theorize that anybody with this genetic trait be more likely to commit rape? What would they do? The potential for "crime prevention" might be high in their eyes, maybe even to the point of pre-emptively arresting and convicting people for their genetics? Think about the potential for false positives; do you think that would stop them from trying to convict "potential" criminals?


    I disagree that DNA is just like a finger-print; the amount of information they can gain, or they can speculate on, is orders of magnitude higher. Anything like this should always under-go major scrutiny, especially measuring the potential for abuse. Politicans and Police Officers CAN, HAVE and WILL abuse whatever powers they are given, history has shown very clearly to me that that will probably never change.

    It's one thing to give Police tools that could be useful in finding somebody who's commited a crime, but i'm 100% against giving them anything that would allow any sort of pre-emptiveness against peopel who "might" commit a crime. Once the police get ahold of a way to do genetic profiling to try and determine potential criminals, it'll be too late.

  • So the way a DNA sample is taken and stored by law enforcement, cannot tell anything about a persons medical history past present or future, it is just a more detailed fingerprint. People argued about storing fingerprints too when they where first, people react way to emotionally about this when they do not know the facts. Britain which uses the short tandem repeats (STR)Analysis cannot tell anything about you, nor is the data stored able to be recreated into something else.

    For years, prosecutors have been fond of citing "statistics" that purportedly show that DNA matching is reliable to "1 in billions". However, this has never actually been established.

    For one thing, the figures cited are founded on the assumption that the DNA sites that are being matched up are individually independent. But they have not established that beyond a reasonable doubt yet.

    Here is an example of what I mean: what are the odds that a randomly-sampled American has the genes that result in curly hair? Relatively low... maybe around 0.2 or so.

    On the other hand: what are the odds that the same person has the genes for curly hair... GIVEN THAT he also has the genes for sickle-cell anemia? That would be pretty high: maybe around 0.99, give or take.

    Individual genes (or lots of them anyway) are NOT completely independent. They depend on others in complex ways that are not yet fully understood. And until we understand more about that, we should be very careful before making claims about the "reliability" of such tests. In certain cases (and there is no reliable way to tell which), the reliability of the test might only be 1 in 100,0000 or even less. That might still sound like a lot, but it is not. That would match 4 or 5 people just in my immediate area.
  • Have to smile at the lack of foresight these people exhibit, implying it's OK to dna-harvest criminals. If that's OK, then all that needs to be done to get a comprehensive database of DNA profiles is to ensure everyone gets arrested for a "crime" at some point. Doesn't need to be much of a crime, and if everyone gets the same treatment, it's just business as usual.
    • ..and there are laws everyone breaks, especially here in the UK, that are simply not enforced. Been practicing your archery lately? No? Get the swabs out.
