They're not using the DNA for either purpose. It's merely to build up their data base.
Well, yes, just as people's names, aliases, birth dates, addresses, tattoos, etc. go into a database. And?
Having watched a PBS newscast tonight, I am against it. Why?
Because until today's ruling the police needed a warrant to collect your DNA. In other words, they had to produce evidence that would satisfy a judge they (the police) had legitimate grounds to force you to give a DNA sample. Now they're free to do so based on what crime you're charged with, not convicted of.
As the article pointed out, and as JtJ just mentioned, they need to be able to make an arrest on a "serious" crime. That absolutely requires probable cause and for most serious crimes an arrest
warrant.
The fact that they didn't specify what constitutes a serious crime isn't at all surprising; the Court obviously wants there to be some room for judicial interpretation. It'll be very clear very quickly if jurisdictions are bringing in people for littering as a pretext to expand their DNA databases and there'll be a lawsuit when that happens.
I don't want the government to have more ways to intrude on us, more ways to invade our privacy. They have already have enough. They don't need even more power over us (which is basically what today's ruling does).
No, it really doesn't. I know it's easy to get paranoid over words like "DNA" and "database" but it's really not intruding on anybody's privacy since, as you yourself point out, with probable cause the authorities can
already test and record the DNA results of suspects.
The more I think about it, the more I support the ruling if for no other reason than it's one less motion/delay to clog up court dockets.
Btw it was Justice Antonin Scalia who wrote the dissenting opinion.
And? That sounds like a good reason to support the other side to me. Scalia can't die soon enough for my taste*.
