Are we decent enough to explore 9 questions re 9/11?

First off, the attacks were cordinated to be within a couple minutes of each other, we couldn't stop them because we didn't know what was going on. If it in fact was an inside job, the people on the inside would have known about things like the date, that would effect the outcome of losses. 9/11 was the first day of school in new york so many people took the day off to take their kids to school. If it had been any other day the world trade centers would have had over 60,000 people in them.
