I'm not defending rapist and child sex abusers. I am simply noting that SOME of the sex laws in our country are a bit too inflexible. Take the example of the young man in GA, who was imprisoned for rape, statutory rape in particular. His girlfriend and he had consensual sex. She even tried to defend her boyfriend in Court. He was maybe 17 and she was 16, I think. He was convicted of statutory rape and labeled a Sexual Predator. As the young man sat in jail, the GA Legislature pushed and changed the law, based upon his case as an example. However, they didn't make it retroactive and he stayed in jail. Finally, a few months ago, he was released when the GA Legislature decided that not making the law retroactive was a bad decision.
Again, there are some real sexual criminals out there who should probably be castrated as well as incarcerated, but as I understand it, not all people labeled
"sexual predators" are deserving of the title, which will stay with them for the rest of their lives.
Regarding the question why they are moving here? Maybe they always lived here, or maybe the sex offender laws don't allow them to live in towns, due to the close proximity of places where they are not allowed to live, such as schools, day care centers, etc.
