The government has examined the investigation of his death,and concluded that Kennedy was killed by Oswald, who fired three shots with a rifle from the sixth floor of the Texas School Book Depository when the presidential motorcade passed by on Nov. 22, 1963. But that has never fully satisfied doubters, and polls have shown that most Americans still believe that someone other than Oswald must have been involved. "the magic bullet" has recently been disprooved when president Trump released the sealed documents related to the cover up of Kennedy's death acidental or not.
