The same way that fingerprints are.

"... no more suspicion that you are guilty of a crime than he would be suspicious of any other random person." I wasn't aware that "random" was the criteria for making felony arrests.

So you voluntarily give your fingerprints then?

There is absolutely no assumption of guilt involved with this. Your fingerprints, your properties, your vehicles...all these exist in databases which the polica already search through without any assumption of your guilt or innocence. This is no different. Go bitch about those databases if you're going to bitch about this one. There is nothing to fear in having your DNA on file unless you have something to fear already.

What happens when there's an amber alert? Shit! The police search through car registrations for a match. I'm being searched without suspicion!

My vehicle's license plate number, make, model, color is being searched for a match every time there is a traffic violation or an amber alert. Should I bitch that my registration should not be on record to avoid suspicionless search?

...and the problem with having your DNA in a database is? Well, aside from the "if you ever do commit a crim you'll be easier to catch" aspect.

So then how do you get arrested for a felony without being suspected of anything?

"“What the DNA Act authorizes is the warrantless and suspicionless search of individuals..." A felony is commited. I find someone I think might do it. Let's call them a...suspect. I arrest this suspect. Now you're saying it's suspicionless for me to take a DNA sample?

Informative?? I think not.
