9/11 Truth Movement

Adherents of the 9/11 Truth Movement dispute the accepted mainstream explanation of the September 11 attacks of 2001 that al-Qaeda terrorists hijacked four airliners and intentionally crashed two into the World Trade Center buildings and one into the Pentagon, with another unintentionally crashing in a field near Shanksville, Pennsylvania. They suggest this explanation contains significant inconsistencies which suggest, at the least, a cover-up, and at most, complicity by insiders.

They analyze evidence from the attacks, discuss different theories about how the attacks happened and call for a new investigation into the attacks. Some of the organizations assert that there is evidence that individuals within the United States government may have been either responsible for or knowingly complicit in the September 11 attacks. Motives suggested by the movement include the use of the attacks as a pretext to start wars in Afghanistan and Iraq and to create opportunities to curtail civil liberties.
