Not so fast. You would jump down my throat for making such an outrageous claim.
Besides it is not legal punishment. If someone decides to take the law into their own hands it is not right. A cop isn't licensed to kill whomever he pleases.

Capital punishment is the counterstrike to murder. If no one murderer then they would not have to be killed. It is wrong to arbitrarily punish someone and I do not suggest we use capital punishment often but there are cases which warrent it.
