This email is a response to a Bureau wide memo sent by Steve McCraw to illicit information from FBI agents who toured through Guantanamo Bay to report any suspected or witnessed abuse of detainees at Guantanamo Bay. This FBI agent states that he witnessed the following: - chaining of a detainee from hand to foot in the fetal position, there was no chair, no food, no water. The author notes, that detainees were often left for 18-24 or more hours in the rooms, causing them to urinate and defecate themselves- very cold interview room, causing a barefoot detainee to shake with cold - very hot (over 100 degrees) interview room, causing the detainee to be almost unconscious and he was literally pull his hair out - very hot with loud rap music playing for approximately two days, with the detainee chained hand to foot in the fetal position. The agent states in the email that the techniques were used by non-FBI interrogators.
