Who let it happen? (Follow the money. Power.)
Who has benefited from 9-11? What politician wanted to be a wartime president? Whose vice president and secretary of defense wanted to go to war with Iraq years before 9-11?
Who had enough information to prevent 9-11? What information HAD risen to the level of their attention while they were ignoring the real perps?
It's easy.
One doesn't have to actually do something. They just have to relax and let it happen.
As Bush, Cheney, and Rice did.
