Cheney and his ilk don't understand liberty, and they don't understand freedom, what it costs and what it's worth. They are small men and cowards, selling out the rule of law at the first whiff of danger.

Until both sides have the courage to recognize themselves in each other, and in the torture pictures, debate is useless. People on the Left are just as capable of rationalizing cruelty as people on the Right.
