I guess what I am trying to point out is if a person is no longer in a U.S. jurisdiction, and not subject to any enforceable registration requirements under U.S. law, how can a state maintain the registration. If you read the Federal Laws related to registration they all refer to "jurisdiction." To me this seems like the publication of information is beyond the "scope" of the law - therefore it would be considered unlawful - even under US Laws.

For instance... If a person is in a particular state they are listed on that website. The other websites for the country do not contain that persons sex offender registration information because they are not in that states jurisdiction.

The states law is pretty vague in the criteria for being required to register in the state. It sounds like if you EVER established an address in the state you are required to register.
