On this 50th anniversary of the assassination of President John F. Kennedy, KETR News Director Mark Haslett places Blacklands Cafe host John Mark Dempsey in the guest chair. In 2000, John Mark edited and published a book, "The Jack Ruby Trial Revisited: The Diary of Jury Foreman Max Causey." John Mark expresses the opinion that based on evidence in the trial and other details that have since been published, he believes Ruby acted impulsively in killing alleged JFK assassin Lee Harvey Oswald.
