If we go on the assumption of good faith and take the reports they're putting out to the general public at face value, they've apparently come to the conclusion that the meeting never took place, case closed. Given that this so-called "new evidence" serves to bolster this conclusion one would think that they would be eager to seize on it.
However, there is a new book out by journalist Stephen Hayes in which he claims that both Tenet and Condoleeza Rice privately believe that the meeting did in fact take place. In light of all the controversy surrounding this topic, this is a rather incredible assertion, and if I were a member of this "Commission", I'd be very interested in talking with Stephen Hayes to find out more about this, although as a journalist it's highly unlikely that he would divulge any of his sources, even under a subpoena.
Personally, I get the distinct impression that they have no real interest in pursuing the matter further at all and would just like it to go away.
The problem - the ones that want to bury it are incompetent. They shouldn't have made a judgment about it in the 9/11 Commission, just like they shouldn't have gone so far to make up a false statement attributed to a named person - Vaclav Havel.
Just calls more attention to the issue.
