Who said anything about Bush? Of course I don't have proof that al Qaeda collaborated with elements within the US government on 9/11. I'm not even saying they were in cahoots. To me, parts of the official version just don't make sense. e.g. no fighter interception, FBI investigations being buried, Hanjoor's flight manoeuvre, Mineta's timeline, put options whose purchaser is not named. They're red flags, not proof. I see 9/11 being treated as a scientific theory where the government version has the advantage of having been provisionally accepted without critique (e.g. collapse of twin towers and WTC7). Evidence has been destroyed or is not accessible. It's going to be an uphill battle to prove anything. The question is do the American people see enough red flags to make them demand a new investigation. No, I don't think the last one was impartial.
