I listened to this all the way through. Apparently a good program was developed by the NSA to listen to everything would-be terrorists might have to say, for cheap, back in 2000. It was rejected in favor of listening to substantially everything, and he resigned in protest against this patent abrogation of the Constitution, and abrogation of what was NEEDED to protect Americans.
He has since evaluated the evidence of a controlled demolition of Tower 7 and reached the inescapable conclusion that NIST did not do SCIENCE. They did not do their work. They did not fulfill their responsibility. He has signed the Architects and Engineers for 9/11 Truth petition, calling for a new investigation.
As I have argued repeatedly, no one familiar with basic science can accept the NIST explanation of the collapse of Tower 7 and this necessarily means that more people were involved than have been identified, and that both Towers 1 and 2 may have gone down the same way.
Given the wars we have fought on the basis of 9/11, this matters a LOT. Was it the Rockefellers in part, as Aaron Russo alleged (credibly)? Who else? Can we escape the sense that a police state was the goal, and fear the means?
