buccal testing for DNA would not and could not be used in any disease diagnosis
So...all those companies that offer to test you for genetic predisposition to a laundry list of conditions are pulling our legs?
This opens the door to creation of a database that contains much more than your identity, unless you want to define identity as every physical thing you are and will be. Further, this cracks the door to collecting such data with NO due process.
Do you not think such a database would be of tremendous interest for a variety of uses?
Hey let's use it for paternity testing, that seems legit.
How about testing for drug abuse tendencies, clear public interest there. Maybe we could make some headway in that drug war?
What about checking the dnadb for a tendency to acquire certain debilitating conditions before hiring positions critical to public safety--police, fire, etc?
Hey, we could examine that dnadb to see if folks are committing insurance fraud. Got yourself a condition, lets just check the old genetic map to see if it's a reasonable diagnosis.
Oh, and we could use it to predict lifespan. That would be tremendously beneficial because we could index your social security payouts to your personalized predicted lifespan. Gonna live a long time? Why we'll just dial the benefits back a bit for you. Just to be fair, you know.
The problem with this is that the information contained in your cellular dna is on the order of 1.5GB--gigabytes. That is tremendously more information than is contained in your fingerprints. These data are the blueprint for all your physical attributes, and likely many of your mental perspectives as well.
Are we really comfortable with the idea that the government, can acquire these data, examine them however they deem appropriate, and store those data in a database (perhaps cryogenically) forever?
Do we believe such a database won't be used for other purposes than simple identification of offenders?
Do we really believe that the temptation to "complete" such a database will be resisted? Perhaps we should be getting a DNA sample from every child that is born, so we can anticipate the lifetime costs to our new federal health system.
Expansion of this system, is already happening right in front of us. First convicted criminals, now arrestees, what next, traffic stops, concealed carry applications?
What possible justification do we have to believe this will not continue to expand, when the official perspective is that DNA testing is just a new fingerprint?
Finally, whatever the current limitations of DNA testing, you can be assured that these tests will reveal more and more about the individual as technology and our understanding of the genome progresses. Perhaps there will be a method of using genetic info to measure things like "resistance to authority." (or whatever personal fear you might have).
Maybe we should get a DNA sample from concealed carry applicants to see if they have any genetic predispositions to violence?
Do you want the government to have such a measure for every citizen?
This decision is ultimately as bad or worse for liberty than Kelo v New London.
