Great idea. Here's another idea, which I posted on a thread earlier today that seems to have died out.
What about a little more barbaric, medieval technique -- like the one used on William Wallace? The sentence of death was read and Wallace was quickly led outside and tied to a team of horses, where he was pulled to a field outside of the city walls, jeered along the way, onto the grounds of the St. Bartholomew Hospital. A massive crowd cheered on as the executioners first hanged him until he was semi-conscious. Then he was tied down and, while still alive, his genitals were cut off and his stomach opened. His intestines were pulled out and burned, all while he still lived. Finally and mercifully, he was beheaded.
"A cruel yet fully deserved death," wrote an observer. Edward was not yet finished with Wallace. As an added deterrent, he ordered Wallace's body cut in four and the pieces brought to cities at the four corners of England, where they were displayed. Wallace's head was impaled on the spikes at London Bridge.
