With the anniversary of the Kennedy assassination recently, a slew of TV shows and articles on that tragic event came into being. One of the more fascinating documentary was on NOVA. One of the biggest source of controversy, and the source for many conspiratorial theory that there was more than one shot at the President on that day was the examination of the way the President's head moved upon impact of the bullet. Many believe that the fact that the video showed the head moving backwards, i.e in the opposite direction that the Oswald bullet entered, showed that there must be another bullet that entered from the front.
The NOVA documentary appeared to have ignored a physics explanation that had been put forward to explain this many years ago. David Jackson, the editor of AJP, expressed his surprise that a well-respected documentary such as NOVA let this observation stood unanswered. He wrote his commentary on this in the Jan 2014 issue of AJP.
But not only that. Due to the anniversary, and wanting to make sure the public knows that there's a perfectly valid explanation to account for what was observed using just a single bullet from the back picture, AJP is making Luis Alvarez paper from 1976 freely available.
Maybe someone from NOVA might get to read it!
