Portions of videotapes of CIA detainee interrogations are transmitted from the foreign countries where the detainees are being held back to CIA headquarters in the US, where they are reviewed by “a small number of officials.” One of the reasons the tapes are made is so that headquarters can check on the methods being used by the interrogators (see Spring-Late 2002 and Mid-May 2002 and After). These methods are said to include waterboarding and other questionable techniques (see Mid-March 2002). It is unclear what happens to these transmitted recordings when many of the videotapes of the interrogations are destroyed (see November 2005). However, in late 2007 an anonymous counterterrorism official will say there is “no reason” to believe the transmitted recordings still exist. [Newsweek, 12/11/2007] A 2003 book by Gerald Posner will also indicate that a team of CIA officials watch the interrogation of al-Qaeda leader Abu Zubaida live on video from an adjacent room. Interrogators in the room wear earpieces so they can immediately act on suggestions from the team. [Posner, 2003, pp. 188-190]
