The idea that a few hijackers, lead by a man in a cave half way around the world were capable of taking down 3 buildings in New York in broad daylight, and damaging the Pentagon, with the most heavily military gaurded airspace in the world... only using airplanes, is a conspiracy in itself. Theres no evidence to suggest that Hijackers with planes did that much damage.  On another note, have you seen how short the Pentagon is? Theres a video showing an extremely fast missle slamming into the side of the Pentagin just a mere feet or two off the ground. There was no plane, yet any evidence that proved so was confiscated and censored. Futhermore back in New York, videos from invesrigative journalists were either edited, or censored aswell, or confiscated. Many videos that were first released have seemingly vanished, with people asking all the right questions. However, theres enough evidence to prove its an inside job becuase of a simple secretive law. States Privilage, which is used by secret agencies to lock an investigation, seemingly overiding the constitution, and criminalizing those whom were locked in the case from speaking further about it, or prrssing charges. This law was created to at first to protect agents working to protect America and the Constitution, but today its being abused ti gaurd imense shadow powers from criminal persecution. May very well be apart of the reason for the fear and silence. But many don't realize the Constitution is the Supreme Law and comes first and foremost. This is why today, many whistleblowers are criminalized and their lives threatened.
