Otherwise, they'll just KNOW that it's torture and put a stop to it! And won't the Japanese be pissed!
Personally, I'd love to do this to the Dimocrats, with a simple question: Do you support the war in Iraq? A response of "no", and WHACK! But then, in order for that to be painful, we would have to find a Dimocrat with actual balls, and that's like finding Santa Claus. We all heard about 'im, but we ain't never seen the real thing. See also: Dimocrat with brains, Dimocrat with spine, and Dimocrat with morals.
They just don't exist, folks.
