Covering JFK: Gunshots ring in Dealey Plaza

As a correspondent for NBC News, Robert MacNeil rode in one of the press buses, seven cars behind President John F. Kennedy’s limousine. The motorcade entered Dealey Plaza in Dallas when MacNeil heard three loud bangs. Judy Woodruff talks to NewsHour co-founder MacNeil about his reaction to the gunfire, before anyone knew the shots had killed the president.
