The point of this torture is not to extract information; there are better ways to do that, which we have long used. The point of this torture is not to extract confessions; there are no show trials of terrorists or auto-de-fes in the offing. The point of this torture is to exercise unlimited, unaccountable power over other human beings; to negate the very point of our country, to our profound and lasting national shame.
Calling this administration "sadistic" insults thousands of sane, decent, kinky sexual perverts.
The first quoted paragraph is backed up by quite a few links (which I didn't copy -- purposely) over at Cosma's blog. Head over there to read the whole thing.
