I'm with others in that I think the death penalty needs to go away. If we assume it has to stay, why wouldn't they just do something like carbon monoxide poisoning, morphine overdose, or sleeping pills + blood letting (no idea if there's an official term for draining blood to the point of death)? They all seem to be far more humane than a firing squad...
