I read "The Bush Crime Family" by Roger Stone and he spells out how Bush was responsible. The man who was responsible for arranging the drive in Dallas was Bush's friend even. Stone doesn't come straight out and say "Bush did it," But there are all these mini smoking guns that combine to form a Voltron smoking gun. Although Bush probably didn't pull the trigger, he arranged it. And he's the only person who says that he cannot remember where he was when he "first heard" that JFK had been shot.
