In 1992, author Dick Russell published one of the longest, most comprehensive and most insightful books on the JFK assassination. This book, The Man Who Knew Too Much (Carroll & Graf, copyright 1992), focuses on Richard Case Nagell, a U.S. intelligence agent who worked for a number of American espionage agencies. Nagell may very well have worked for the KGB and CIA as a double, triple or quadruple agent. The first part of the interview highlights Nagell’s involvement with the Kennedy case and centers on many of the points discussed in Update on the JFK Assassination (see above). In the interview, Russell also discusses the history of his involvement with Nagell’s story and sheds more light on the circumstances surrounding Nagell’s death. The broadcast explores: the probable role in the assassination of former staff officers who had served under General Douglas MacArthur (notably General Charles Willoughby, MacArthur’s German-born former intelligence chief); a number of overlapping and interlocking fascist organizations which figure in the investigation; the possible use of mind control on Lee Harvey Oswald and a number of warnings of JFK’s impending murder that preceded the killing.
