All I know is that the sex offender registry idea ain't working too well.
The sex offender registry is was and will always be a horrible idea. It's a list of dangerous people we allow to live in our communities. Sounds insane to me. If they are known to be dangerous predators then they should not be let out of a cell, ever.
On the other hand, 11 year old boys slapping girl's butts at school get added to the registry, so on the one hand the system is inadequate in protecting us from actual dangerous people and on the other it's making lifelong victims out of people who committed rather innocuous acts.
Abolish the registry. Child molesters and serial rapists aren't people who just slipped up and made a mistake, they are mentally defective in a way that makes them dangerous to their fellow man. Recidivism is too high and rehab is almost completely ineffective.
My non-scientific opinion is that whatever a person "needs" for sexual satisfaction, especially beyond a certain age, is pretty much hard wired in. If an old man only finds forced or coerced sex with children to be sexually satisfying then that's that. To reform him you have to convince him to be a monk and abstain from sexual satisfaction altogether. Sexual urges and desires do not die easily. For instance, there is no amount of rehab you could do on me to make me stop being attracted to women and start being attracted to men. None. If society told me that if I continued wanting to have sex with women they'd have to lock me up I could maybe fake it but in reality I would still want to have sex with women. So, really, if they wanted to stop me they'd have to kill me or lock me up.
I don't support allowing child molesters and serial rapists out of prison ever. Once we've got 'em it is immoral to release them back upon more innocent victims. A silly *** registry is a violation of a person's right's imo, and not an effective tool on the other.
