California Expands DNA Identification Policies 42
The Los Angeles Times is reporting on a new California policy to match the DNA of suspected criminals to the criminal's family members in order to use them as investigative leads. Use of partial DNA matching is drawing fire over privacy concerns from citizens and law experts. FBI officials are hesitating as well, though their concern is that the courts will not accept such techniques. Quoting:
"The policy, which takes effect immediately, is designed to work like this: The state's crime lab will tell police about DNA profiles that come up during routine searches of California's offender database and closely resemble, but do not match, the DNA left at a crime scene. (Previously, the state refused to tell police about these partial matches.) When such partial matches do not surface or fail to produce a lead, a more customized familial search can be done in which computer software scans the database proactively for possible relatives. The software measures the chance of two people being related based on the rarity of the markers they share."

With DNA, you're using a DNA sample from a crime scene and matching it to a known criminals DNA to find a relative.
What you're suggesting is using a fingerprint from a crime scene, matching it to a known criminal, and then using that to find the persons relatives. That doesn't make the slightest bit of sense. If the fingerprint matches, you know your criminal. If it doesn't, you've got to keep investigating. Who they're related to isn't exactly important.
In this case we're talking about casting suspicion over people simply because their DNA is close to someone else's- that's frightening.

How would you like a detective knocking on your door and wanting to discuss your immediate relatives, looking for leads on a case he's working on?
"we have reason to believe that one of your relatives committed a crime, care to answer a few questions?"
Now lets say it was a really close match and now they would like to DNA test your kid to see if he's a 100% match? (with no other evidence than this close match) If you allow that, then where do we draw the line? Not so close? Can we DNA test all your cousins? We're sure one of them's the one we're looking for!

Worse still is when the fact of "legitimacy" is then used to judge the person(s) in entirely separate venues, such as job related security background checks conducted on the otherwise innocent family members. Although society may change and the "legitimacy" question cease to matter as much as it used to, others will hang on longer and tighter, such as in this example, where the employers will view it more negatively than the population because they'll be looking for the potential problems, and pursue them on this basis "just in case".

Can you be sure that in all this time there won't be another government where, say, Sippenhaft [wikipedia.org] will be considered a legitimate tool again? Or, with all your citizen's DNA in a database it'll be easier than ever before to screen for certain 'types'. NO political power can permanently resist the temptation to expand the (ab)use of this data.
Consider how much information - and thus power - is associated with your DNA. It's not just an account number or a name on a birth certificate, it's what you are, your most personal biological information.

Any sort of study to find the answer would have very loud political repercussions, thus is unlikely to ever be done (or been done - we'dve heard about it).
The odds may be millions when compared to the entire polpulation of a region, but can not be known without mapping the genetic clustering. The numbers may be much, much lower inside genetic clusters.
Without knowing how to account for genetic clustering and localized optima, the actual rarity of genetic markers in a specific case can not be known. And the difference will always favor the police by producing false positives.
After a few years of collecting DNA from the poorest, the police may be able to link any crime with someone in that community if 'familial' relationships are used as indicators. I've never seen *any* comment in articles about forensic DNA testing that discusses this. Which is why, if on a jury, I will almost certainly disregard any DNA evidence.
