Selectively editing the record on 9/11

What did Bush know before 9/11 attacks? This is the question the Bush administration doesn't seem to want the world to know the answer to, as it is doing its damnedest to keep the 9/11 commission from getting an unedited view of the President's Daily Brief (PDB) before the attacks.

The NY Times reports that a deal has been cut to allow the White House to selectively edit the PDB documents before they are turned over, to the chagrin of an umbrella group of victims' families and two Democrats on the 9/11 panel.
