The Wizard discovered that Frank Sturgis was there, inside the Dallas PD too.
It sure looks like a match to me.
Now, think about it. If this was just a case of psychotic Oswald shooting Kennedy for no reason- just because he saw the motorcade route in the paper- which is the official story, then what would Frank Sturgis be doing there? He traveled from South Florida to Dallas just to watch Kennedy ride by him, did he? He was that much of a fan, was he? Frank Sturgis' being there is, by itself, a smoking gun that the official story is a despicable lie.
