JFK: The Lost Bullet helped kick off this month's JFK documentary blitz on National Geographic. Since then, there have been practically one or more on the air each day looking into every angle imaginable. There's been Nova: Cold Case JFK, The Lost Kennedy Home Movies, JFK: The Final Hours, and Kennedy and the Cuban Missile Crisis. On Friday, there will be multiple TV look-backs, including JFK Assassination: The Definitive Guide on History and Tom Brokaw Special: Where Were You? on NBC.
