A conversation with Warren Commission Assistant Counsel Burt W. Griffin, Case Closed author and Lee Harvey Oswald scholar Gerald Posner, and JFK conspiracy theory debunker Michel Gagné.

Shermer, Griffin, Posner, and Gagné discuss: the nostalgic myth of "Camelot" • Lee Harvey Oswald and why he killed Kennedy • Cuba, Castro, the Bay of Pigs debacle • the CIA and why it is rational to be skeptical of their activities • the "magic bullet," pristine or predictably damaged? • James Hosty and the FBI's files on Oswald before he killed JFK • CIA and FBI coverups • General Edwin Walker • Jack Ruby • Bernard Weissman, • common themes in conspiracy theories • witness intimidation • planted evidence • evidence tampering.

Burt W. Griffin, Warren Commission Assistant Counsel was the assistant counsel to the president's commission on the assassination of President Kennedy (popularly known as the Warren Commission) and had primary responsibility for investigating and writing the section of the commission's report (1964) on whether Jack Ruby was engaged in a conspiracy to assassinate either JFK, Lee Oswald, or both. He lives in Shaker Heights, Ohio.
