@Mor - It kind of bothers me that they are so easy to place though. I mean, I'm not a criminal or anything, but I do know that my prints are in the US system, because I was a Peace Corps volunteer and we had to submit a set of prints as part of the entrance application.
I'm not planning on robbing a bank or anything like that, but what if I want to protest about something that the government isn't happy about and they use my fingerprints against me one day?
On the other hand, there have been a lot of serious crimes solved using fingerprint evidence. I don't know where the line should be against the government collecting them.
