My question involves criminal law for the state of: Colorado, If I had a sexual assault charge with a minor who was 17, in California, in 2008, finished probation without violations, have no other new criminal charges since, do I have to register in Colorado? My charge was a misdemeanor and my theory of thought is the age of consent in Colorado is 17, and there has to be a comparable charge in the state you move to, so why would I have to register in a state with a consent law of 17? If I need to register, when and how do I get any relief from this law(s)? This charge is one of the least offensive?
