Enhanced interrogation techniques is a euphemism for the U.S. government's program of systematic torture of detainees by the Central Intelligence Agency (CIA), the Defense Intelligence Agency (DIA) and various components of the U.S. Armed Forces at black sites around the world, including Bagram, Guantanamo Bay, and Abu Ghraib, authorized by officials of the George W. Bush administration. Methods used included prolonged stress positions, hooding, subjection to deafening noise, sleep deprivation to the point of hallucination, deprivation of food, drink, and withholding medical care for wounds — as well as waterboarding, walling, nakedness, subjection to extreme cold, confinement in small coffin-like boxes, and repeated slapping or beating. Several detainees endured medically-unnecessary "rectal rehydration," "rectal fluid resuscitation", and "rectal feeding." In addition to brutalizing detainees, there were threats to their families such as threats to harm children, and threats to sexually abuse or to cut the throat of, detainees's mothers. There has never been an authoritative tally of the number of detainees subjected to these methods, or of how many died under torture. The CIA admits to waterboarding three people implicated in the September 11 attacks: Abu Zubaydah, Khalid Shaikh Mohammed, and Mohammed al-Qahtani, and (although not admitted) the agency waterboarded Abd al-Rahim al-Nashiri; photos show a waterboard surrounded by buckets of water at the Salt Pit, a prison where the C.I.A. had claimed that waterboarding was never used. Three reported suicides at Guantánamo are alleged to have been homicides under torture; no criminal charges have been brought for these or for acknowledged torture related homicides at Abu Ghraib and at Bagram.
