I think that sex offenders only have to register if they are out on parole, not if they are being let out at the end of a sentence, which is really dumb especially in cases like this where you KNOW that the guy has had no benifit from being in prision and probibly doesn't care about going back. Since he has been in jail so long, more than likely it won't take him long to realize that he had a better life in jail than he ever would on the outside. So of course, it is highly likely he will re-offend.
I'd feel really safe too. I hope for his and the communitys sake that he DID reform in prision and he wont harm anyone else.
