"No conspiracy theory" except for the one where 19 individuals allegedly hijack four aircraft and crash them into buildings. If you believe the official account. I remember watching this thinking, "he's trying to oversimplify the issue. He's trying to make it as though it's not important enough to find out about."
Aside from the fact that 2,973+ people were murdered, 2 wars have been waged, 70,000 have gotten sick, our civil liberties have been compromised, our country has been bankrupted, our Constitution has been spit on, and our status as a country has been destroyed, nope, I guess nothing happened except, "the planes hit the buidling, the buildings came down."
What a tool.
