Oh dear.
Well i have another solution that may actually protect children. Legalize realistic sex robots. Maybe we dont have the tech yet, but soon as its possible then they should be issued to pedophiles so they can use the dolls instead of real children. Now if you have a problem with this idea then there's something wrong with you. Or you like the idea of children being harmed...

Of course you'd ideally want the pedophiles all killed or castrated, but lets face it that legislation is much harder to pass and you know it wont happen, and on top of that you need proof that a person is a pedophile in the first place so it wont stop first time offenders.
