Screw legality! When can private groups of citizens get their hands on this software to lure child molesters to their deserved deaths by beating? Nothing else will keep perverts from using the Internet to find victims.
I would think parental supervision over possible violation of someones rights could keep child molesters from finding victims. I completely and totally agree that people who prey on children are dispicable and probably should never get out of jail due to the recitivism rates.
Just think an ounce of prevention on the parents parts would keep us from having to cross the moral line ourselves to give them a pound of cure.
