I mean, come on. Do you really think this sort of thing is sensible to do?

Nice balance.

If you show signs of criminal-in-the-future-behavior, you should have your DNA obtained and cataloged for future scrutiny every time there’s the least suspicion that you might have committed a crime, or even been near one at any given time. (Like a burglary in your neighborhood.)
