Why do we torture

Phillipe Sands, writing in Vanity Fair, will walk you through it if you have the stomach for it.

The abuse, rising to the level of torture, of those captured and detained in the war on terror is a defining feature of the presidency of George W. Bush. Its military beginnings, however, lie not in Abu Ghraib, as is commonly thought, or in the “rendition” of prisoners to other countries for questioning, but in the treatment of the very first prisoners at Guantánamo. Starting in late 2002 a detainee bearing the number 063 was tortured over a period of more than seven weeks. In his story lies the answer to a crucial question: How was the decision made to let the U.S. military start using coercive interrogations at Guantánamo?

The Bush administration has always taken refuge behind a “trickle up” explanation: that is, the decision was generated by military commanders and interrogators on the ground. This explanation is false. The origins lie in actions taken at the very highest levels of the administration—by some of the most senior personal advisers to the president, the vice president, and the secretary of defense. At the heart of the matter stand several political appointees—lawyers—who, it can be argued, broke their ethical codes of conduct and took themselves into a zone of international criminality, where formal investigation is now a very real option. This is the story of how the torture at Guantánamo began, and how it spread.

And at the end of the day these men went home to their families, kissed their wives and children, smiled at their neighbors across perfect lawns and slept well at night.
