Here’s what I don’t get about this. The 9/11 Commission conducted a 20 month inquiry. Didn’t Commission staffers have access to this material on their own? If so, isn’t it possible/likely that one or more of them would have seen any document that Berger would want to remove/alter before last Sept/Oct.? Particularly the after action report? Wouldn’t that be one of the first things you’d want to look at? If I’m right, why would Berger take the risk of hiding something that might already have come to the Commission’s attention?
