"Reasonable Doubt" is one of the first documentaries to legally use the Zapruder Film to prove JFK was not shot by a lone assassin. It has nothing to do with whether there was a conspiracy or who was behind the conspiracy or whether Oswald was involved or not. There is nothing about the subsequent investigation and the Warren Report. There is nothing about LBJ or the mob or the CIA or Castro or the Illuminati. The documentary is one hour devoted to looking closely at the Zapruder Film to prove there was no way only one weapon was used to kill the president. The documentary does what it sets out to do, with cool precision. A great and important film, originally created for The Discovery Channel but ultimately airing on the Arts and Entertainment Channel.
