Hour 2: After the Kennedy Assassination, Americans were left to wonder what might have been had the president continued to govern. So how can we assess a presidency that was cut short? We’ll pose the question this hour to Mark Samels and Susan Bellows. Their American Experience documentary JFK will screen tonight at Studio Movie Grill at 7 p.m. A panel discussion will follow. You’ll also be able to see the film on KERA Channel 13 November 11th and 12th.
