We have known it to be wrong always. We have done it always. We humans I mean. Perhaps it sometimes leads to useful facts, more often it does not. Calling it enhanced something-or-other is ridiculous. Torture is like art or porn. We know it when we see it. If you are treating somebody in a way that you yourself would not like to be treated, in the hopes of getting them to tell you something, you have to take a hard look at yourself.
Thomas Jefferson was a hypocrite and a coward. He is my least favorite founder. But the man could write, and he said this. "I tremble for my country when I reflect that God is just."
