A DOD Contract Linguist stated that he was involved in at least two questionable interrogation techniques while on duty in Iraq. An unidentified interrogator choked a detainee with a rope noose, lifting the detainee up slowly until the detainee stated he would talk if let down. The interrogator then lowered the detainee to the ground, whereupon the detainee gave a confession. An Air Force Office of Special Interrogations Agent then placed a gun to the temple of a detainee until he confessed. The memo states "It is believed that the above situations, as described, are questionable techniques as defined by law and regulation. It is our understanding that agents must report any such action to their RAC immediately".
