Plausible Denial: Was the CIA Involved in the Assassination of JFK? is a 1991 book by American attorney Mark Lane that outlines his theory that former Watergate figure E. Howard Hunt was involved with the Central Intelligence Agency in the assassination of United States President John F. Kennedy.[1][2] Published by Thunder's Mouth Press, the book chronicles Lane's legal defense of Liberty Lobby, a right-wing political group that was sued for libel by Hunt after it published an article in its weekly paper, The Spotlight, linking Hunt — a former CIA operative — to the assassination.[1][3] According to Lane, Thunder's Mouth Press agreed to publish it "after every other publisher in the United States had refused to do so".[4]
Lane's chief source for Plausible Denial was Marita Lorenz, a woman contacted by Lane during the suit who provided a deposition stating that on the day prior to the assassination she transported guns from Miami to Dallas where she met Hunt, Frank Sturgis, and Jack Ruby.[5] In the book, Lane states that the CIA arranged the assassination of Kennedy because Kennedy had planned to destroy the Agency.[5] Others put forth by Lane to be involved in a conspiracy include George H. W. Bush and George de Mohrenschildt, whom he implicates as CIA agents.[5]
In the book, Lane harshly criticizes the media for its failure to cover the trial and its unwillingness to even consider Kennedy assassination theories[6] as having credibility.
