I was never part of those "Truth Movements." They are somewhat silly. Heckling Mayor Bloomberg won't get you anywhere.
But obviously something isn't right about the 9/11 Commission Report. So many holes you can run a plane through them. Max Keiser is putting out a film on the 9/11 Put Option trades in which the amount of bets against airline stocks right before the date were astronomically high and outrageous, which would lead to proof of prior knowledge of the attack other than the supposed terrorists who couldn't land aircraft.
But of course, the government wiped out information on those trades, which isn't surprising. Obviously the official "story" is just that, a story. The real truth of what happened will probably never be known.
