Bloody nonsense. Do it the military way.
If he is a terrorist, decapitate him by the good old machine invented by Dr. Guillotin.
If he is a freedom fighter, drum him out with the death roll to the ramparts of any fortification (Pentagon?) and have him shot by a platoon, the coup de grace applied by an officer ( I should'nt like to be this man: I'm no hangman).
But this depends on twelve men brave and true.
