In the coming months I will do some posting on my thoughts about these motives.
Key-elements in that posting will be:
the personal relationship between Jackie and JFK, Mary Pinchot Meyer and Mary Pinchot Meyer's suspicious 'murder-case'.
A first problem, having a stand-in, is not that easy
Stand-ins weren't needed: JFK, Jackie and the Connally's turned out to be the best actors themselves..
Alternatively, having the president surviving the shoot-out you still need a warm body in the seat when you arrive at the hospital.
The whole scene in and around Parkland Hospital was also staged, it was all part of the simulation.
The main problem is what you would do with a surviving JFK afterwards; it could get somewhat embarrassing should he turn up in a TV show or so
The media-involvement was essential in this hoax, so that's all under control.
would now like to put in another question: Why use such a complicated set-up?
It is evidently possibly to shoot from the 6:th floor and have a high kill-rate if you shoot while the car go towards you. You don't need any fancy weapon either, and if the shooter empty the gun into the car, this make the pattern of a mad-man.
If you have help at the hospital, you can arrange so that death is certain. The advantage would be that claiming a single shooter would be a bit easier.
The purpose of the JFK psy-op was to simulate his 'murder' in plain sight, not to actually kill him.
In any case I agree with the findings by the JFK researchers
Never follow 'Truth-Leaders', always use your own eyes and braincells...
