Meanwhile a newly released FBI memo shows U.S. officials had grave doubts on the effectiveness of the coercive interrogation techniques used at Guantanamo Bay. One FBI agent concluded that the interrogations produced intelligence that was “suspect at best.” The memo containing this conclusion was originally released by the Justice Department last year. But at the time the department blacked out the agent’s conclusion that the intelligence was suspect. FBI agents and officials have complained about numerous interrogation techniques used including the shackling of detainees to the floor for periods exceeding 24 hours, without food and water. The agents also complained about detainees being draped in Israeli flags and the use of growling dogs to scare detainees.
