Actor Richard Belzer talks about "Hit List" May 6, 2013 at the National Press Club. The book is billed as an in-depth investigation into what some see as the mysterious deaths of people linked to the President John F. Kennedy assassination story. Belzer describes the assassination as the "greatest murder mystery" of all time" - linking the deaths of fifty people, including columnist Dorothy Kilgallen, U2 pilot Gary Powers and Jack Ruby, the man who killed Lee Harvey Oswald. Belzer also presents evidence supporting the theory that there were two Lee Harvey Oswalds and how his death was set in motion by the FBI, the CIA, and the Mob. Belzer insists there is a timeline and there are witnesses who have proved that Oswald never fired a shot the day the president was killed in Dallas.
