WARNING: This is the actual film that shows JFK getting shot in the head. It is not for the faint of heart.
The camera, understandably, was jostled around quite a bit in the commotion. This Stable Pan allows the image to remain steady within our field of vision. Never mind that the stabilization was done by a conspiracy theorist who insists the film itself is a fake...
Watch the reactions of the driver and the other riders in the car. How would you react in a crisis situation like this? Perhaps the strangest (yet somehow understandable) response is from the first lady. When she gets up and reaches behind the car, it was often stated that she was trying to help the secret service agent behind the car to hop up before the car drove away. She is actually reaching for a piece of the president's skull that had flown onto the back of the car. You can see her grab it and then get back into her seat as the car speeds away.
This woman calls the cops on a pair of robbers as they are robbing her home - while she is at work and watching things unfold over a webcam. Pretty tense.
Make sure to stick around to the end to hear the Harry Potter theme.
