In a Joe Rogan interview with filmmaker Oliver Stone (who famously made the conspiracy film about JFK’s assassination, JFK), the two discussed what really happened. In the original investigation, the Warren Commission, lawmakers came to the conclusion that Oswald fired three shots and that he acted alone.
However, Stone claims that there were four or five shots fired, and that the idea of the single bullet going through JFK to Connelly (i.e. the “magic bullet”), makes no sense. Consequently, many people today still believe that there was a second shooter on a “grassy knoll” in Dealey Plaza that the FBI wanted to cover up.
