That he was assassinated cannot be in dispute. Shot in the back walking home in a low crime area with no possessions stolen. Not unlike a certain incident in downtown Dallas in 1962. But as with that assassination it’s clear the Democrats are worried where a genuine investigation might lead (spoiler: a retired Dallas County sheriff deputy, who had been serving at that time, told me everybody in his department knew LBJ was behind it. Not sure I believed him but he said it was an open secret among Dallas law enforcement).
1963 ... all thumbs.
