Yes, 100,000 people participated in setting up 9-11 and kept secret for national security reasons. LOL. Like I said. What would be the reaction when they realized their preparation was for mass murder of 3000 of their own countrymen? Think a couple of them may have been a tad pissed? Or somebody covering up the event having a bout of conscience?
Why after 10 years has NOBODY come forward with a deathbed confession that they were a member of the team that rigged the explosives, or they had a hand in falsifying evidence, or they were a member of a team planting airplane parts at the Pentagon, or...well, you get the point. Your position on 9-11 is irrational in the extreme.
