Senate report on CIA program details brutality, dishonesty

An exhaustive, five-year Senate investigation of the CIA’s secret interrogations of terrorism suspects renders a strikingly bleak verdict of a program launched in the aftermath of the Sept. 11, 2001, attacks, describing levels of brutality, dishonesty and seemingly arbitrary violence that at times brought even agency employees to moments of anguish.

At one point in 2002, CIA employees at a secret site in Thailand broke down emotionally after witnessing the harrowing treatment of Abu Zubaida, a high-profile facilitator for al-Qaeda.
