Its very easy to happen. All you need to do is apply for any number of Federal or local governmental jobs or even for a handgun carry permit and youre likely to have your prints taken. Im 70 right now. The first time my prints were taken was when I was 18 and applied for a summer job on a railroad. Then there was the Army, then a carry permit, then another job. Having your prints taken in connection with a criminal matter is only one small way they are likely to be taken.
