Here's a 1968 episode of The Dick Cavett show discussing the assassination of Robert Kennedy

It's fascinating to see this round table discussion on The Dick Cavett Show about the assassination of Robert Kennedy. People had the same concerns about gun violence 50 years ago, but the way people talked about it on TV in 1968 is inconceivable today. The panelists were allowed to speak for more that 15 seconds without being interrupted, and the other panelist appeared to be listening to what the others were saying. The panel consisted of actor Robert "Man From U.N.C.L.E." Vaughn (a politically active friend of the Kennedys), NAACP executive director Roy Wilkins, psychiatrist David Abrahamsen (author of "A Study of Lee Harvey Oswald: Psychological Capability of Murder"), and broadcast journalist David Schoenbrun.
