On November 22, 1963, just as President John F. Kennedy's motorcade is getting underway at Love Field Airport in Dallas, Texas, local television cameras captured an image of a "shrugging" Secret Service agent who had been running alongside JFK's car. Former SS agent Clint Hill explains who "Shrugging Man" is (and what he was doing) in this excerpt from a November 8, 2010, C-Span interview.
