Nah, they have multiple classes. His would not be considered a predator so would end up on the list for a shorter time frame at least that's what the various lists I've checked indicate. I'm not sure why your post is moderated as informative when it is factually incorrect. They have life-time registrants but those are for predatory offenses in every list I've ever looked at.
Also, few of those other things you mention are laws (in most states) but are probation conditions. They're generally free to live most anywhere (and certainly are after they've been removed from the list in cases like this), attend school, etc... Notification is the law, that much is true I think?
This could have changed but I was recently checking an area where I was thinking about buying some property and it was still the same there.
