Beyond a Reasonable Doubt examines how conspiracy theories developed after publication of the Warren Commissions 1964 report into the circumstances surrounding the JFK assassination. Using the evidence compiled by the commissioners, the authors demonstrate how and why the report was rejected by the American public over the past five decades. The book also provides new and compelling evidence which reveals not only Oswalds guilt, by this clear motive which was never satisfactorily addressed by the Warren investigation. The book also looks at the way in which conspiracy writers have succeeded in persuading a majority of the American public that Lee Harvey Oswald was either an innocent Patsy or acted in conjunction with others to assassinate the president. In an examination of the modus operandi of conspiracy writers, Ayton and Von Pien reveal how the public was manipulated into accepting conspiracy allegations and of how their theories were built around nothing more than misinterpretations and misrepresentation of the evidence and crude speculation.
