Jackie Kennedy to her dying day cursed “that little Communist” who killed JFK. RFK, who you would think would be amenable to “getting” conspirators also thought Oswald acted alone. The whole problem with the investigation is that Kennedy had a lot of enemies, and Dallas wasn’t friendly territory for Kennedy. Therefore you’re going to get a lot of blind leads leading nowhere. If someone shot GWB, there would be the same level of conspiracy theorists, but the most likely culprit would be some deranged leftist loser or jihadist.
Sorry, I don’t think it can be said RFK believed in a single gunman.
“President Johnson didnt believe the Warren Commission; nor did Robert Kennedy, as David Talbots new book Brothers shows, Mr. Stone said in an e-mail message. In 1979, the House of Representatives Select Committee on Assassinations determined that President Kennedy was probably assassinated as the result of a conspiracy. The Warren Commission, deservedly, has not stood the test of time.” - http://www.nytimes.com/2007/05/14/books/14jfk.html
Odd turn of words:
Nuts believe in a JFK conspiracy but those who don’t believe in a lone nut.
