The USA sure is hiding something about this whole 9/11 attacks, i dont understand how Bin Laden would first deny involvement in the attacks but later confirm that it was him and it was really convenient how the media got a video of Bin Laden discussing the attacks with someone on tape.
For me there is no mystery. I'm pretty sure that these attacks were organized without the help of U.S. intelligence. Maybe because bin Laden killed so he couldn't give an explanation in court.
