RFK Must Die: The Assassination of Bobby Kennedy is a 2007 investigative documentary by Irish writer and filmmaker Shane O'Sullivan. The film expands on O'Sullivan's earlier reports for BBC Newsnight and The Guardian and explores conspiracy theories related to the assassination of United States Senator Robert F. Kennedy on 5 June 1968. The title comes from a page of "free writing" found in assassin Sirhan Sirhan's notebook after the shooting upon which Sirhan had written "R.F.K. must die - RFK must be killed Robert F. Kennedy must be assassinated... before June 5 '68."

Plot

The film features many interviews, including one with Sirhan's younger brother Munir, who talks about his brother's upbringing and perceived injustices. Other interviewees include Paul Schrade (a union leader who was shot during the assassination), Sandra Serrano (a witness who saw two people gleefully running out of the Ambassador Hotel after the shooting) and Vincent diPierro (a witness to the assassination). Lengthy audio clips are also provided that attest to Serrano's forceful manipulation at the hands of Los Angeles police sergeant Hank Hernandez and Sirhan's extreme suggestibility to hypnosis.
