I don't even know what Mr. Sheen thinks about the subject. I just sort of assume that he thinks Bush did it.
His theory is that Bush ordered the tower blown up, and set up explosives throughout the towers. And the plane to hit it, to cover up the demolition. Without hitting the wires. Of course.
It's more than a tad kooky. We're talking full fringe Internet conspiracy theorist. No doubt the reptiloids are ultimately behind the attack, pulling Bush's strings.
