John F. Kennedy Jr. was killed on July 16, 1999. The last Kennedy who possibly could have made a difference died in an accidental plane crash according to the official reports. Official reports seldom tell the truth but exist to cover up the crimes. The corporate media, the same then as today , whitewashes the story.
John Jr. was going to run for the New York Senate. He would have won. Hillary Clinton would have been delegated to the dust bin of history and the U.S. political scene could have been much different than it is today. Of course the argument could be made that if he had not died then, other attempts would have been made. The threat against the established order was too great . He had to die.
Essentially, the same cabal that killed his father killed him.
WRH has an account of why the official story is in doubt:
