Ex-CIA chiefs are lining up to criticize the Justice Department's probe into the agency's treatment of terror detainees, but the investigation may end up being a relatively small one. According to The Washington Post, the probe is set to look at only a few cases—less than the 10 that have been previously reported. One case that's drawn the probe's attention is the November 2002 death of an Afghan man in a CIA facility in Kabul known as the Salt Pit, after he was allegedly beaten and chained to a concrete floor without blankets. In that case, hypothermia was officially given as the cause of death, but investigators did not have access to the body—raising questions about if that was part of a coverup. Seven CIA directors this week called on President Obama to cancel the inquiry, which they warn would be demoralizing and weaken intelligence-gathering efforts.
