Read the report in its entirety. Read dozens of other official reports from various agencies. Probably read a few thousand official articles. Have watched probably a few thousand hours worth of footage. Have debated the subject endlessly for years. Through it all - not one piece of solid evidence has ever been produced by the truthers. NOT ONE. The official 9/11 report has TONS of physical evidence pointing to what normal people believe to be the truth. The official 9/11 report contains testimony from experts that have all been involved in the investigation. Not a single person involved thinks it was a conspiracy of any sort. Sorry, you don't have space between your ears, it's completely full of shit at the moment.
