I think it would be unfair to just decide to behead them. We should have like a lottery, or contest, where people can submit suggesions for execution methods, I for instance think we should throw them off of high places, like the grand canyon, or a skyscraper. Maybe from Mount Rushmore from teddy roosevelt's head.

Others might prefer to bend back tree limbs and tie them to their limbs, then release the bent limbs to have the tree recoil and tear them apart, trult a classic. Or a large heavy rock being put over them that crushes them for days.

We could have a game show even to determine it, or a contest of some sort.
