Thankyou for pointing out what Dragadon said also...

hm, if super heroes doesn't work, what would work then?
I don't think the cops can do so much more, they too must sleep and be at their families too.

Of course Super Heroes wont work. There is no way for anybody to know if someone is a killer/rapist/paedo before they do something. If they do get caught in the midst of something however, they should be emplanted with a chip. If they attempt to try anything after that (They would be tracked, so if they went near a school and had sexual desires) they should either be caught or the chip to emit a electrical current that would kill them.

That or publicise their wereabouts etc to the whole country. Im sure they would have a field day. Especially the Ex-KKK members who have been low on 'fun' these days.

Wow, you can read after all.:D

But I already Knew that before Drag said it anyways. Things happen everyday.
