Did Lee Harvey Oswald Assassinate JFK?

Fernand Amandi in his "Conspiracy Theories and the Public" class at the University of Miami interviews Gerald Posner, author of "Case Closed: Lee Harvey Oswald and the Assassination of JFK," and Steve Gillon, author of "Lee Harvey Oswald: 48 Hours to Live: Oswald, Kennedy, and the Conspiracy that Will Not Die." Posner and Gillon argue that Oswald alone killed Kennedy.
