the assassination wasn't "solved"

     People remain interested in the assassination of John F. Kennedy because, in a way, it couldn't be "solved".  After Kennedy was shot, a suspect was arrested--Lee Harvey Oswald. While moving Oswald from one jail to another, Oswald was shot and killed by a man--Jack Ruby--standing among the spectators. Here in the United States, we can't try the dead, and Oswald was dead. We have the right to be confronted with the witnesses against us, which can't occur if the accused is absent or dead. So there was no trial for Oswald--just the Warren Commission, which did investigate the murder. Conspiracy theorists have been busy ever since.
