CIA videotapes of detainee interrogations are held overseas and not sent back to CIA headquarters from the time they are made (see Spring-Late 2002) until the time they are destroyed (see November 2005). They are stored in a safe at the CIA station in the country or countries where the interrogations are performed. Given that there is concern about keeping such highly classified material overseas, it is unclear why the tapes are not sent to the US for security reasons. [New York Times, 12/19/2007] However, portions of the tapes are transmitted to the US so they can be viewed by CIA managers (see Between April 2002 and November 2005).
