Human Rights Watch is absolutely correct that lethal injection is inhumane. However, its reasoning is wrong. Lethal injection is inhumane because it lets the murderer off too easily. There really is only one fair and just method of capital punishment, and that is for the murderer to be put to death in exactly the same manner in which he or she did in the victim. If murderers are to be shown mercy when they are executed, then the least they could do is show mercy to their victims.
