Read Thomas Mallon's piece about alternative universe fiction. He includes Stephen King's latest book 11/22/63 in his list. Of course King says that LHO did it as a lone assassin. (I wonder who paid him to do it. He probably made a ton of money.)

Mallon reinforces the lone assassin theory in his criticique of King's novel. Mallon wrote "Ruth Paine's Garage" a  a disinformation book about the Kennedy Assassination. Mallon is a good friend of the Bushes, especially Bush senior one of the Kennedy Assassination conspirators.
