froomkin has a good discussion about bush's non-denial about his involvement in the destruction of the CIA interrogation tape.
actually, i wouldn't be surprised if there weren't more interrogation videos out there somewhere. and i also wouldn't be surprised if some of them might eventually become public. they keep referring to the 2002 video as a "tape." so it probably was recorded at the tail end of the VHS era. once you go to digital, copying becomes a whole lot easier and faster to do. that means the video content will be harder to control.
