Ducking, pulling Lady Bird on top of him, same thing, he hid when the shooting started. And for him to hide behind or underneath Lady Bird, what a piece of crap.
As far as LBJ being part of the plot, nothing in that article says anything about that except; Before he died, LBJ told his old friend Tom Janos “that he knew Oswald had not killed JFK alone.” This does not mean LBJ had any part in it other than knowing it was going happen and that more were involved than Oswald. LBJ knew the mob did it.
