Why would they try to pull off something so risky, when they already had an apathetic and compliant public pre-9/11. The political payoff doesn't match the match the danger they would be placing themselves in. I think the fact that these consiparcy theorys have an traction speaks to how polarized american politics have become, people are so wrapped up in the us vs. them mindset that they've begun to see the other side as evil. Mr. Chomsky makes some good points, a lot of these people are no better than Ann Coulter, making outlandish claims just to sell books.
