Yeah,but he could easily of been forced by the US government to say that so they could blame the arabs for planning 9/11 so they could invade that part of the world for oil.
Why doesn't the US government show the hidden footage of the plane that hit the Pentagon?There is footage from a near by hotel that shows better images of the so called "plane" the hit the building,but the CIA confiscated the images...why?
Because they got bored of conspiracy theories, and didn't want to have to cope with yet another one.
IMO, Al-Qaeda did it, not even the US government would be ruthless enough to destroy 3000 lives in one go, or decimate their stock market.
