This time I talk with Dr. John McAdams, a political science professor at Marquette University and an expert on the assassination of President Kennedy. Dr. McAdams teaches a class on the assassination and he has written a book on the subject, JFK Assassination Logic: How to Think about Claims of Conspiracy, but he is probably most famous for the material he provides online at jfkassassination.net and the news group he oversees, alt.assassination.jfk.
