9/11 Conspiracy
On 9/11 a terrorist attack resulting almost 3,000 deaths and the collapse of the World Trade Center. Theorists believe that higher government officials had advance knowledge of the attack, but did nothing, as they saw it would be a good way of justifying good reasons to go to war. Government investigations claim to have found no evidence supporting the theory, but people believe there is evidence, the officials have just overlooked it, or maybe even ignored.
