I agree if you are 100% sure that someone is guilty of a heinous (sp?) crime then they should be killed for it. Maybe give them at most one appeal. Lethal inject s about as painless as being killed gets, so there's nothing cruel about it... especially considering what kind of cruel crime you have to commit to be charged with the death penalty.
Personally I think they're being let off too easy... and wasting our money with life imprisonments and lethal injection these days.
What's the current price of a .45 round?
