Capital Punishment has been tried before - wither it be mob lynching - burning at the stake, stoning -through to the trendier modern means of hanging - electric shock, or lethal injection. One thing to be considered is - it's effectiveness, in terms of deterrence. According to all informed sources - Capital Punishment fails to serve this purpose. Alas for those who demand revenge - this vitally important concept, is regretably ignored by those who bully - for the death sentence.
It is purely a thirst for blood - a mark of the primitive man. All civilised people would condemn such state brutality - for the act it surely is.
