Some of us have been writing for years (see this and this) that the 9/11 Commission Report was unreliable because most of the information was based on the statements of tortured detainees. As I wrote in March 2007:
In fact, the 9/11 Commission Report was largely based on a third-hand account of what tortured detainees said, with two of the three parties in the communication being government employees.
I have also previously written that Senator Leahy’s desire to base a torture investigation on the 9/11 Commission was problematic.
Now, Newsweek is running an essay by Philip Shenon saying the same thing:
The commission appears to have ignored obvious clues throughout 2003 and 2004 that its account of the 9/11 plot and Al Qaeda’s history relied heavily on information obtained from detainees who had been subjected to torture, or something not far from it.
