The Commission concluded that Oswald acted alone and was the sole shooter, firing three shots from the book depository window. They found no evidence that the Dallas Police were in collusion with Jack Ruby. They found no evidence that Oswald and Ruby were connected to any conspiracies, foreign or domestic, in the assassination of President Kennedy. The Commission could find no definitive motive for Oswald’s actions. Criticism, skepticism, alternative explanations, and conspiracy theories immediately abounded upon release of the Commission report. Books, movies, lectures and investigations have proliferated since that day in 1963, to the point that few people accept the conclusions of the Warren Report. Even members of the Commission and President Johnson himself, now all dead, expressed doubts about some of their conclusions. The main conspiracy theories suggest, or in some cases, absolutely assert, that one or a combination of the following characters were behind the assassination: Vice-President Johnson himself, Fidel Castro, the Russians, the Italian Mafia, the CIA, FBI, Secret Service, or other government agency.
