I don't listen to conspiracy theories that are characterized by one dominant feature - they ask questions, but don't present EVIDENCE. As in, how would you PROVE what happened at the Pentagon, given a scenario where no one saw it, no one heard anything, and everybody woke up to a big hole in the building. How would you go about PROVING it was a missile? Where's the forensic evidence, the explosive materials, the patterns, the delivery system, the trajectory, the point of origin, the paper trail for the purchase and placement of the missile, the persons involved.
Basically, if you were to try to convict someone in court for firing a missile at the Pentagon - the kind of evidence you'd need to even GET a trial.
And there isn't any. There's only conjecture and doubt, and where there is a LACK of evidence, some magic hand-waving saying it's all covered up.
Has anyone figured out that in order to blow up two or three World Trade Center buildings, you'd have to wire the damned thing for weeks, with explosives? Do you think - SOMEONE - would notice? Is there any intelligent reason why we have rooms full of intelligence and interrogations outlining exactly how it was done, who did it, how they financed it, trained the men, got them in here - CLAIMED CREDIT FOR IT - while the conspiracy theorists ONLY have that the data is secretly hidden away somewhere?
It's a joke. I feel sorry for anyone stupid enough - and blinded by their own political dislike - to believe anything like this.
