Marshal Evans is a well-known expert on the JFK assassination which is now over 55 years ago.
Marshal's book, JFK The Reckoning, details many of the elements of the assassination that debunk The Warren Commission which essentially was a whitewash that concluded that Lee Harvey Oswald was the lone gunman who was solely responsible for the assassination of John F Kennedy.
There is so much information about the assassination and so many conspiracy theories that surround the event in Dallas on November 22, 1963 that we may never know exactly what happened.
