When the CIA destroyed those prisoner interrogation videotapes, were they also destroying the truth about Sept. 11, 2001? After all, according to the 9/11 Commission report, the basic narrative of what happened on that day - and the nature of the enemy in this war on terror that Bush launched in response to the tragedy - comes from the CIA's account of what those prisoners told their torturers. The commission was never allowed to interview the prisoners, or speak with those who did, and was forced to rely on what the CIA was willing to relay instead. On the matter of the existence of the tapes, we know the CIA deliberately lied. Why should we believe what we've been told about what may turn out to be the most important transformative event in our nation's history? On the basis of what the CIA claimed the tortured prisoners said, President Bush launched ... an endless war that threatens to bankrupt our society both financially and morally. How important were those key witnesses" to the 9/11 Commission report? Check out the disclaimer on page 146 about the commission's sourcing of the main elements laid out in its narrative: "Chapters 5 and 7 rely heavily on information obtained from captured al Qaeda members ... Assessing the truth of statements by these witnesses ... is challenging. Our access to them has been limited to the review of intelligence reports. We submitted questions for use in the interrogations, but ... were told that our requests might disrupt the sensitive interrogation process." Videos were made of those "sensitive" interrogations, which were accurately described as "torture" by one of the agents involved, John Kiriakou, in an interview with ABC News. Yet when the 9/11 Commission and federal court judges specifically asked for such tapes, they were destroyed by the CIA, which then denied their existence.
