was it? he gave up after a few seconds. he seemed to be making that video for one reason only.
And what reason would that be?
The guy in question is Christopher Hitchens, a right-wing columnist. He is famous for having once said that waterboarding is "extreme interrogation" but not torture.
He accepted the challenge of being waterboarded in order to test this viewpoint. Needless to say, his opinion has now changed:
You may have read by now the official lie about this treatment, which is that it “simulates” the feeling of drowning. This is not the case. You feel that you are drowning because you are drowning—or, rather, being drowned, albeit slowly and under controlled conditions and at the mercy (or otherwise) of those who are applying the pressure.

I apply the Abraham Lincoln test for moral casuistry: “If slavery is not wrong, nothing is wrong.” Well, then, if waterboarding does not constitute torture, then there is no such thing as torture.
