This post has a video with excerpts of a man being waterboarded. Decide for yourself.
Lots of attempts to say torture is a gray issue in the video, I notice. Lots of talk about defining and regulating it. I admit to being a good (old-style) conservative on this issue. Principle: no torture. Exceptions: none. Defition of torture: oh come on, stop weaseling. One of the few things I agree with Dershowitz on -- we all know what's torture, we all know the US is doing it and let's stop pretending.
