Okay, I'll be the first to jump into the fire...
In my opinion: Government funded propaganda. Whole lot of evidence just does not add up to what we are being handed.
Like: From the 9/11 commission report--the 'terroist' that supposedly flew the plane into the Pentagon is claimed to be both--poor in his flying skills and the best that they had b/c the route to hit the pentagon would be a difficult one.
The instructors from the training facilities in FL reported that he could not (or barely) get a Cessna off the ground.
Larry Silversteen (owner of the complexes) said in a PBS documentary called America Rebuilds that they 'pulled' WTC 7. That is slang for demo-ed it.
PNAC documents (Project for a New American Century--Cheney's work) states that they need a "Pearl Harbor like event" to get America behind invading Iraq/Afghan.
3000+ people were murdered--I don't dispute that, I just don't believe that 19 terroists did it.
