What they should do is put a hand grenade in his mouth with pin attached, tie one end of a long wire to the pin and the other end the the bumper of a truck. Drive the truck slowly and keep increasing the speed until the pin is pulled and his head is blown off.
I like that idea!
One improvement...have a raffle to see which of the possible victims gets the honor of driving! Proceeds go to some sort of "Neighborhood Watch" to catch MORE of these BA$TARDS!
I like your idea better than mine.
There was a movie with Rutger Hauer and Gene Simmons where Hauer dispatched him with a grenade in the mouth. I'll never forget the line---
" You're not a soldier...you're a fly, on a pile of s--t."
You are too kind. Just use the firing cap in his mouth. When it pops in his mouth he'll be able to look back at himself.
