TRUTHERS: if 9-11 was orchestrated by our govt, why not claim these terrorists all come from iraq?

I don't fault anyone for asking questions. As long as they actually want the answers to those questions then then ask away. But if you can't accept the truth no matter what evidence is presented, then you are just wasting everyone's time. I'm an engineer, I've studied physics chemistry and construction. Those buildings reacted precisely how I would expect them to from an aircraft impact. There was absolutely no evidence of extra explosives involved. The collapse was completely in line with the laws of physics. There is no mystery there. If they can't accept that, then I can't help them. By all means ask your questions, but don't claim its a conspiracy just because the answers are not what you want them to be.
