This piece in today's New York Times outlines a number of the presumed truths about 9/11 which the 9/11 commission report effectively debunks. Among them:
The commission's report found that the hijackers had repeatedly broken the law in entering the United States, that Mr. bin Laden may have micromanaged the attacks but did not pay for them, that intelligence agencies had considered the threat of suicide hijackings, and that Mr. Bush received an August 2001 briefing on evidence of continuing domestic terrorist threats from Al Qaeda.
Link to NY Times story, Link to downloadable report, and here is Kottke's helpful outline of the lengthy report's structure.
