Messrs. Graham and Gurr had both served on the staff of the commission appointed by President Johnson to study violence in America following the assassinations of Martin Luther King and Robert Kennedy. Our guests are serious students of their subject and don't use the term "violence" as a devil word (for example, Mr. Gurr cites the vigilante movement on the American frontier as having succeeded in maintaining order in regions where there was no lawfully constituted authority). WFB: "Is it historically nonsensical to say, as for instance Arthur Schlesinger said after the assassination of Mr. Kennedy, that 'We killed Mr. Kennedy, we killed the three most idealistic people in public life during a period of three years, and we have therefore justified the odium of the world'? Or would you simply dismiss that as emotional reaction?" TRG: "I would not be prepared to share Mr. Schlesinger's collective guilt." WFB: "Would you be prepared to disavow it?" HDG: "I would disavow it." TRG: "Personally I'd disavow it." HDG: "I have been told by black militants that I killed Malcolm X."
