Which set of facts do you believe?
I believe that a load of muslims, mostly saudi arabian hijacked a number of planes carrying many innocent men women and children. They then deliberately flew those planes into the twin towers resulting in their complete destruction and killing many more innocent people, including many emergency services personnel. Anybody who gives credence to any conspiracy theories about this event is ignoring the fact that the number of people who would have to be involved, and relied on to stay silent forever is mind boggling. Simple as that, therefore anybody who gives credence to conspiracy theories about this event is a total dhead.
