It is not known where precisely in the Hashemite kingdom they are being held, but they are thought to be at a secret facility belonging to Jordanian intelligence or at a secret base. Their detention outside the U.S. enables CIA interrogators to apply interrogation methods that are banned by U.S. law, and to do so in a country where cooperation with the Americans is particularly close, thereby reducing the danger of leaks.
According to the Human Rights Watch report, the CIA was granted special permission by the U.S. law enforcement authorities to operate "other laws" at the secret facility with regard to interrogation methods. Detainees are subjected to physical and psychological pressure that includes the use of simulated drowning, loud music, sleep deprivation, and sensory deprivation. Some of these methods were exposed with the revelation of torture techniques used by American interrogators at the Abu Ghraib prison in Iraq.
