I too don't see the difference between taking a DNA sample for a national database and taking a fingerprint which is added to the existing national database. Shucks, my fingerprints are on file because I was in the Army. My wife's are on file because her father had a Top Secret clearance. They want my DNA, I don't care (as long as it doesn't hurt). I don't see what the heck they're going to do with it -- it's not like they can match it to anyone else.
