To 9/11 Truthers: Is there any real evidence that 911 = inside job?

There wasnt enough evidence at the scene where an aircraft hit the pentagon, that alone says for 100% fact there's something really sad and political going on, Sad because it was really sad particularly for any one who lives within visual range of the Twin towers, Political because bush just sat there smiling like an idiot with a children s book in his hands after hearing of the news, what kind of moron does that, any one who actually cares about American lives would have jumped up and gave the order to scramble all fighterjets.
