It's true, torture works. It works on those administering it. Just look at that waste of oxygen
known as dick Cheney. You ever seen a more damaged human being? He promotes torture like sears promotes tires for sale.
every intelligent, knowledgeable and informed human knows that torture is for vengeance and terrorizing of subjects. The notion that some sort of insight or valuable actionable information is to be gained by use of torture is nothing more than a red herring argument.
It does accomplish one thing, it dehumanizes those who apply the various forms. Anyone who can comfortably administer torture to another human being and say that that is an acceptable manner in which to behave and has no deleterious effects on him or her is whistling past the grave yard.
Torture is like war, it is a representation of failed efforts at reasonable actions. War is failed diplomacy and torture is failed interrogation. Both usually the consequence of ignorance and laziness on the part of the aggressor.
