The fact that FEMA explained away Kenney's error without even bothering to mention the fact that they had an exercise planned for that morning, and therefore Kenney may very well have been on the scene getting ready for the exercise and wasn't mistaken, is deeply troubling, as it evidences knowledge of guilt. In fact, it is even possible that Kenney was mistaken (although we've seen absolutely no evidence that he was, and his story is consistent with Giuliani's testimony), but Giuliani's testimony combined with FEMA's failing to explain what was really going on is proof that FEMA felt that the truth would be damning. It is even more damning when we consider that the exercise, named TRIPOD, was supported by the Office of Justice Programs, through the Office for Domestic Preparedness, with the Office for Domestic Preparedness personally headed by Dick Fuck Yourself Cheney. The number of unexplained and officially unacknowledged 'training exercises' in and around all aspects of 9-11 are starting to pile up. If you anticipated that two huge buildings in New York City were to be knocked down on September 11, it would be prudent to have a presence in New York City on September 10. The best way to cover up such an unexplained presence is by calling it a training exercise. It is quite likely that the NORAD standdown was accomplished in the same way, with both the air traffic controllers and the local NORAD commanders under the assumption that anomalies in flight routes and behavior of the 9-11 attack planes were part of a training exercise, and thus were ignored until it was too late.
