The CIA videotaped its interrogations of two terror suspects in 2002 and destroyed the tapes three years later out of fear they would leak to the public and compromise the identities of U.S. questioners

Oddly, that's a valid reason to have destroyed them, but given how often things have been done with a stated purpose that is then demonstrated to be bullshit, I can't say I buy it. Of course, it also protects the identities of questioners from the courts who may be interested as well.
