The book depository is only about 80 yards. The Grassy knoll fence is maybe 30. The two story rail control tower behind the grassy knoll is 120. Guys at the fence claiming to be secret service turned away a motorcycle cop who charged up the hill immediately. Secret Service says they had nobody there.
Of course it was a team. And Oswald was duped and not part of it. Probably Naval Intel and told he was there to watch for something etc. As he said, he was a Patsy.
Then mobster Jack Ruby, silenced him.
It was a hit. CIA overwatched and used mob and Cuban exiles. Oswald was the designated nobody to take the blame. He was supposed to be killed by Tippet.
The part most idiotic is that Oswald had no plan to escape. No car nearby, nothing. That is because he thought he had a ride from the team. His big plan? Walk home and get his 38? And then walk to a theater? If he was gonna do it that day he woulda had the gun right there and had a plan.
The grassy knoll is in Zapruder’s film. No assassin noted.
