Olaf Koenders pointed me to a better YouTube video, which I slowed down below. It shows an incendiary round striking the upper right side of JFK’s skull, knocking his head backwards, and burning for the rest of the sequence below. Note the streaks of the flame in frames 319 and 320, showing how rapidly his head was being pushed backwards by a shot which had to have come from the front, the opposite direction of Oswald’s location.
Had the bullet exited the front of his skull as claimed by the Warren Commission, the incendiary material would have also exited.
Obama just banned incendiary ammunition from public lands, because it was causing a lot of fires.
