An email by an FBI agent regarding an observation of a non-FBI approved tactic being used on a detainee at Guantanamo Bay. The FBI agent reports observing a detainee sitting on the floor of a room with an Israeli flag draped around him, loud music being played and a strobe light flashing. The agents presumes from a nearby person's uniform that this practice was being used by the Department of Defense/Department of Homeland Security. All FBI personnel were told not to take part in any such interviews or interrogations which fell outside the FBI's policy of interviewing detainees.
