The internet is funny, Lizzie... you can find 29 people who will swear that dinosaurs rode in the Ark with Noah. Once you accept certain premises, anything can be shown to follow. MOST of those "Firefighters, The Police and The Scholars" were nowhere near the WTC... and the ones who were have no particular reason to claim better expertise than the ones who did the careful digging, measuring, testing, etc. for the official reports.

You never DO explain how so many managed to hide such a huge conspiracy.
