No, I don't believe that Bush caused 9/11. I did wonder why Bin Laden's family were flown out of the US when he was being batted around as a suspect. No questioning, no interviews, just 'get your ass on the jet maam'. Moore attempts to find reasons for this, which may amount to nothing more than wild speculation on his part, but as a Republican, I was more than a little angry at the time, and the Executive branch has never sated it. Are you simple minded enough to trust not just bad reasoning, but no explanation at all? We morons aren't.
