How do we "re-form" the mind of someone who becomes sexually aroused at the sight or thought of a child?
If my Malinois bites someone whom she perceived as a threat to me, there are city ordinances in some states that require her to be put down.
If a Pedophile who victimized numerous children gets out of prison, while they do have to register with local government as a sexual predator, and inform their neighbors, they're still entitled to live in our neighborhoods where our children are. And because they've paid their debt to society.
While still a Pedophile, now free in our community. And for as long as they live remain a threat to children.
The world is going crazy.
