I think it's one of those questions you ask because you know the answer to it already, but you ask to make others either think about it or realize that they know the answer too. I work for attorneys, and a good attorney doesn't ask a question he/she doesn't already know the answer to when they're in court. The point of it is to make others say the answer out loud, she's trying to wake people up by their own testimony.

But I agree - hang one of these assholes and yes, the rest will sing like canaries. In fact, hang them on the White House lawn with a camera crew so the whole world can see what happens.
