Contra is not interchangeable with anti, and neither of the two are words, so I'm not "contra" anything.
I don't think it's right for the government to collect that information. Our entire legal system operates on the assumption of "innocent until proven guilty", so if I am assumed to have not committed a crime, what justification is there for keeping my fingerprints and DNA on file to match to a crime? If they have just cause to believe I'm involved in a crime, the government can go through the proper procedures to obtain that info, and until then they can fuck off.
@atmonauti: I'm sure you'd never even notice, I'm a very peaceful person by nature. It just so happens that the person in question is a shitstain alcoholic who I can't imagine ever doing a worthwhile thing with his life, and after throwing a plastic lawn chair he decided to get first in my friend's face, and then in my face trying to pick a fight. He was drunk off his ass or I'm sure he would've been a lot smarter than to challenge 3 people bigger than him, especially when at least two of them basically do not value his life, and would not feel bad at all about him dying.
