#10 - 9/11 did not come up on Bin Laden's list of crimes on the FBI's Most Wanted list because they did not have enough "hard evidence" to indict him.
#8 - Reorganization of the chain of command made it impossible (summer of 2001) for the planes to be intercepted by the American military & war games simulating events similar to the attacks made it confusing for air traffic controllers to ascertain what was going on.
#7 - Giuliani was given advance warning by the OEM that the Towers were going to collapse.
#2 - The "hero" sits in an elementary school while the attacks take place. The Secret Service did not react to the news even though this event was announced weeks before & al-Qaeda would have known where he was which placed not only the President in danger (who it is their responsibility to protect), but also the children & staff who worked in the school.
