I'm not against capital punishment either, but there are "better" ways to die. I recognize that ancient communities needed to get rid of murderers however a decapitation (like in Japan) seems to me a more humane way of execution than the thing these monkeys do.
Speaking of modern days though, I don't see how such acts can be tolarated by national or international laws(?). The only conclusion I draw is that the leaders of those countries are either some pussies who are afraid of the public or psychopaths.
