Why does the government/police always have to have conspiracy theories about criminal activity? Unless of course it´s a question of a single perpetrator, lone gunman that sort of thing.
9/11 is understood to have been a conspiracy carried out by Islamic terrorists, followers of Sayyid Qutb's brand of Wahhibi fundamentalism.
Well, I think the government´s conspiracy theory about 9/11 is the dumbest one of them all which of course is understandable because everything in that theory had to be signed off by ALL members of the government appointed commission tasked with preparing that theory.
