And from Starbucks, I went down the rabbit hole. I found myself at a conference on Walker Street called 'How The World Changed After 9/11'. It was packed, but I managed to slide in at the back, to hear a guy called Webster Tarpley chant his own list of names. The names of the 46 military exercises and hijack drills (called things like 'Vigilant Guardian') that were actually taking place on the morning of September 11. "The greatest density of drills in US military history," Tarpley said.

...

What I heard, from speaker after speaker, was a heartfelt desire to turn away from the path of destruction, militarism and lies that America has been set upon after 9/11. Ray McGovern, a former CIA analyst, mourned for Iraq: "One million dead, 4m displaced, and that's a victory?" He sees the failure of Americans to comprehend the scale of the destruction wrought under their flag as nothing less than racist.

...

He drew attention to an extraordinary story, barely touched by the mainstream press, that Richard Clarke, who was the White House counter-terrorism czar at the time of the attacks, has recently accused the CIA of deliberately suppressing information before 9/11, information that might have prevented the attacks. Clarke claimed: "There was a high-level decision in the CIA ordering people not to share information." And who made this decision? "I would think it would have been made by the director".
