DESTROYING EVIDENCE…. The New York Times reported in December 2007 that the CIA “destroyed at least two videotapes documenting the interrogation of two Qaeda operatives in the agency’s custody” in 2005. The videos in question included the interrogation of Abu Zubaydah, and remain the subject of an ongoing criminal investigation.

As it turns out, “at least two” was a dramatic understatement.

New documents show the CIA destroyed nearly 100 tapes of terror interrogations, far more than has previously been acknowledged.

The revelation Monday comes as a criminal prosecutor is wrapping up his investigation in the matter.

The acknowledgment of dozens of destroyed tapes came in a letter filed by government lawyers in New York, where the American Civil Liberties Union has filed a lawsuit seeking more details of terror interrogation programs.

“The CIA can now identify the number of videotapes that were destroyed,” said the letter by Acting U.S. Attorney Lev Dassin. “Ninety two videotapes were destroyed.”

Destroying two interrogation videos is obstruction of justice. Destroying 92 interrogation videos is a systemic cover-up of widespread lawbreaking.

As the ACLU noted, the U.S. Attorney’s letter “provides further evidence for holding the CIA in contempt of court. The large number of videotapes destroyed confirms that the agency engaged in a systemic attempt to hide evidence of its illegal interrogations and to evade the court’s order.”

And let’s also not forget that the CIA’s explanation for all of this has never made a lick of sense.
