I see what some of the comments are getting at; what we do now seems to have little effect. I could just as easily say the same about theft, murder, or assault. I have never seen anything keep these predators away from potential victims better than steel bars and barbwire. How do you propose to fix this, if you don't think prison is working?
After all is said and done, it is the victim that should be the object of our concern, not the criminal. The criminal makes a choice for both themself and their victims. The victim is the one that has no choice, especially our youngest citizens.
