Freedom to Fascism
You may have heard of Aaron Russo's film America: From Freedom to Fascism, but maybe you didn't watch it because the title turned you off. Admittedly, the title makes it sound like some extremist-conspiracy-nut-job flick.
I can assure you that it is not. I bought the DVD when it came out, watched it, then donated it to my public library so others could watch it. The director has since graciously made the film available for free via Google Video. This is required viewing for all true American patriots and truth seekers. Furthermore, there is an excellent interview with Ron Paul in the film.
