i could agree with amsterdam, seems to be the only logical solution at the present time, but it needs something more....we don't want to have proof of what these people are doing, we need to stop it before it happens, once it happens the child will face the pain for the rest of their life.....so they stilll need to be able to be put somewhere kids will not venture, and if they stray outside that boundary (the predator) then police are immediately dispatched to throw them in prison
