Although I semi agree that killing paedophiles is not a wise thing to do... who ever killed this sick old perv didn't seem to give a shit about such things as human rights or what you or I may think and going by the reports of this brutal killing it sounds like revenge.
Think about it Jon...if say this old fucker had raped your child...wouldn't *you* want to kill him. I know I would be tempted.
AND BEFORE I get shot down for not feeling compassion for paedophiles...I simply don't. Sorry.
I don't know what the answer is, but people who find children sexy need to go seek specialized help.
