What about that chemical that supposedly makes people far more likely to tell the truth?

Honestly, I don't think the U.S. or any other nation that claims to be "civil" should torture. Capture people, if they wont talk, press them as hard as you can, but dont make them think are about to die, or rape them, or humiliate them. There is nothing civil about that and if anything it just proves you intelligence agency to be shite.
