The 9/11 Commission co-chairs don't believe the 9/11 Commission Report:
The 9/11 Commissioners knew that military officials lied to the Commission, and considered recommending criminal charges for such false statements, yet didn't bother to tell the American people (free subscription required).
The co-chairs of the Commission now admit that the Commission largely operated based upon political considerations.
Chairman Thomas Kean says “I’m upset that [the government] didn’t tell us the truth.”
Co-chair Hamilton says of the CIA's cover up and destruction of tapes of interrogation of people allegedly connected with 9/11:
"Did they obstruct our inquiry? The answer is clearly yes," says Lee Hamilton, who co-chaired the 9/11 Commission, in the wake of reports the CIA destroyed videotapes of interrogations of two al-Qaida suspects. "Whether that amounts to a crime, others will have to judge," adds Hamilton.
Hamilton also says "I don't believe for a minute we got everything right", that the Commission was set up to fail, that people should keep asking questions about 9/11, that the 9/11 debate should continue, and that the 9/11 Commission report was only "the first draft" of history.
