Maybe this is a question for Aaron to answer. I see many states are now requiring sex offenders who were convicted and served out their sentences to register long after they have been released from parole, probation or other holds. How is this not double jeopardy in sentencing when the sentence has been completed before the advent of the Megan's laws? I have been a bit confused about the law that would let what amounts to a re-sentencing after the completion of sentence. Could you perhaps enlighten me? And where does the U.S. Constitution stand on this? Also states Constitutions. Your thoughts please. Thanks.
