The answer to this problem is for the first offense to be life in prison, no parole. I am talking about predatory child molesters, those who prey on YOUNG children, not the statutory rape stuff. They don't usually change and if they do change they can suffer the consequences for their crimes in prison.
Nothing will change until we get sentencing reform.
Make that death. God gave us capital punishment/death penalty for a reason. To remove dangerous people from society. Society shouldn't have to keep paying a penalty for what these pos' do.
