I was watching the SM Holland interview with Mark Lane recently (who IMO offers the most damning evidence of a shot from the front) and noticed this photo at the end. I had never seen it before but it was included after Holland said JFK was hit so hard by the shot from the knoll that it "flipped him over" and his foot was hanging over the car door.
You don't really see this in the Zapruder film but is this true?
