DNA Records and Privacy

So California is considering a law that allows/requires law enforcement to collect DNA samples along with fingerprints and pics of folks picked up for felony crimes. If the person is later acquitted of felony charges, the DNA file(s) may be expunged (or gotten rid of, I suppose), although probably only by some sort of written request and forms filling, etc.

Some say this is an invasion of privacy.

Fingerprinting is NOT the same sort of invasion? I think they are the same.

And, as things stand now, the only people who need to fear having their DNA filed are people who have committed felonies in the past, or PLAN to commit felonies in the future. If I am not a former, current, or potential felon, what reason do I have to sweat about it?

Some day it may be possible for filed DNA records to be used to make a race of atomic mutant monster clones of me, producing a mighty army of killer bloviators! Yikes! Eek! Flee for your liiiiiiiiiives!

Or, perhaps, some totalitarian government may assume power and decide that everyone with the "prone towards heterosexual interests in females" code are threats to society and can hunt us down and execute us. Yeah. That's gonna happen in MY lifetime.

The only downsides I can imagine are just that ... in my imagination, and in this case, highly improbable.

So I say, get the sample and see if we might not be able to put away a few more felons BEFORE they rack up a higher score of violent crimes, stopping some serials from becoming so legendary, and saving even a few more lives.
