Isn't DNA confidential Medical Information? Supreme Court Decision Chips away at Constitution.

Taking someone’s DNA and holding onto it should be illegal, unless that person has committed a crime. DNA should be considered private medical information.

It’s nothing like a finger print or facial image. Maybe later they can clone the individuals and develop a nameless army of assassins made up of genetically lawless jaywalkers and speeders. Bloomberg:

FELDMAN: …Or why we should worry about the Fourth Amendment. “If DNA sampling was actually like fingerprinting, this argument might be convincing. But of course it isn’t. Fingerprints are a phenotype that reveals nothing except a random pattern that no two individuals share. DNA, however, is your genotype: the blueprint for your entire physical person. If the government has my fingerprints, it’s like they have my randomly assigned Social Security number. If it has my DNA, it’s like they have the entire operating system.” Noah Feldman in Bloomberg.
