I saw an interview with Dershowitz a while back about torture. He basically said 'You do what you gotta do, and you keep your mouth shut about it'.
This seems to be a major point that about 3/4's of the people who work for the United States government seems to have missed and/or ignored!
BTW, I saw him say that, too; I had to look more than once to make sure it was HIM doing the talking.
