The 50th anniversary of John F. Kennedy's election is leading to a resurgence in attention to his assassination and the conspiracies about who did it. The latest entry comes from author James Douglass, in his new book JFK and the Unspeakable. His theory: The Pentagon and CIA plotted to kill JFK because they were upset that the military hawk had turned dove and wanted to end the Cold War, not win it. Douglass concludes that JFK was shot not from the top of the Texas School Book Depository but from the front of the car. He suggests Lee Harvey Oswald was set up to take the blame, that he didn't shoot Kennedy, and that he was gunned down before he could tell his tale. And, he writes, Oswald's killer, Jack Ruby, was in on the plot and supplied JFK's unknown killer.
