Thats all just a drop in the bucket. Bush not reacting whatsoever for 20 minutes when he was told, unskilled pilots having the ability to fly jumbo jets and hitting their targets, the way the buildings fell, building 7 mysteriously falling, finding one of the highjackers passport on the streets of NY an hour after the buildings fell, Bush fighting against a 9/11 investigation, ignoring bin Laden, etc, etc, etc, it all adds up to bullshit.
Bush has already shown he will lie to invade a country at the expense of a hundred thousand lives yet people would rather believe some dude surrounded by sheep in a fucking cave half way around the world did this...puh leese.
