This is the full documentary prison interview with incarcerated James E. Files, who admitted to being the individual situated on the Grassy Knoll at Dealey Plaza in Dallas, Texas, and responsible for firing the fatal shot at President John F. Kennedy. After an FBI tip, Kennedy assassination investigator Joe West found James Files serving time for the attempted murder of an Illinois police officer. At first, Files was reluctant to talk, but West persisted and established a relationship with the man with first-had knowledge of various aspects of the world of organized crime, government operations, and key people involved in planning and carrying out the assassination of President John F. Kennedy.
