Maybe the CIA attorney did give permission to destroy the tapes.

[[The story of the CIA's tape destruction took another twist today. Earlier, Mark Mazzetti had written that the destruction of the tapes angered the CIA's legal counsel, John Rizzo. Today, Mazzetti and Scott Shane report that the CIA's attorneys gave permission to destroy the tapes of interrogations that included waterboarding:

Lawyers within the clandestine branch of the Central Intelligence Agency gave written approval in advance to the destruction in 2005 of hundreds of hours of videotapes documenting interrogations of two lieutenants from Al Qaeda, according to a former senior intelligence official with direct knowledge of the episode.
