Terror Storm. This is the latest offering by Alex Jones. It covers much more than just 9/11. It plumbs the depths of False Flag operations throughout history and is extremely relavent to our current situation. Probably his best movie to date.
911 The Road To Tyranny - Alex Jones
Martial Law 9/11: Rise of the Police State (Alex Jones)
Loose Change 2nd Edition - Korey Rowe / Dylan Avery / Jason Bermas
This is the film that has been sweeping the nation.
This an abridged version of investigative journalist Daniel Hopsicker's film "Mohamad Atta and the Venice Flying Circus." One of the first 9/11 videos I viewed. Unfortunately I was unable to find it in it's entirety as a streaming video, but since this really opened my eyes to the lies and obfuscation going on in the media I wanted to include it as a stub at least because this flick is well worth watching.
