I’m in Oklahoma. The set-back here is 2000 feet from schools, day care, parks. I tell people to watch the local news. In any given week there will be 3 to 5 sex offenses reported on. You will be told one of two things about the alleged offender. Either he/she was on the registry or was not. In neither case did the registry prevent the alleged crime. It is a way for legislators to sound off as being tough on crime and make brownie points back home.
I was a sex offender. I was a high school student. I served my sentence. I graduated from high school. There is a comparison in there somewhere. Keep looking, you’ll find it.
