I'm reminded of something Christopher Hitchens once wrote about this sort of 'defence in depth', which I'll try to recount as best I can: One often hears from undemocratic regimes that they aren't torturing people in the manner accused, and that if they were it wouldn't be so bad, and that if it were bad it would still be well justified. On hearing these three in combination, little doubt should remain that the accusers have it right.
