Well, I certainly don't think that the Discovery documentary is disinformation from some government source. I'd recommend the documentary to anyone interested in the JFK assassination. As someone who was skeptical about the magic bullet, it has pretty much convinced me that it could have happened. The point of the film, as aforementioned, isn't to prove whether Oswald was the lone gunman or not, but that the shot fired known as the "magic bullet" could have occurred and was successfully recreated.

I also highly recommend the History Channel/A&E's documentary, The Men Who Killed Kennedy.
