One interesting observation about the assassination is that when JFK was shot, Jacqueline tried to leave the vehicle by crawling over the seat and over the back. She didn’t try opening the door and getting out.
It is natural to move in the most direct away from the person trying to kill you.
It suggests that one of the bullets may have come from the front seat, possibly the agent who was the passenger.
The story I heard was that she was trying to retrieve a piece of his brain 🧠that had been blown out by the head shot and it landed on the trunk lid.
or the driver
She was retrieving part of his brain.
