They should let the people go all medieval on their ass, old school pitchforks, and torches, and bring back witch burnings.
One special last time, just for them, suspend UN rules, and give them what they really deserve, then reinstate humanitarian/torture rules, after all those fuckers are fried to a crisp, or hung, after a long torture.
have a little eye for eye action( everyone of them who hurt children, should have to experience the same pain/ the same torture)
Get some big long thick tools/clubs/poles, and simulate what a child must have felt like.
Instead of cork screw metel rod sticks they used on children,, use big heavy industrial drills.
