Hi John, I don't have your talent for photo illustration but the arrow here indicates the impact point viewed from the front and rear. There was a theory that what we see from the front view is part of someone behind JFK's shoulder, which seems like a good explanation, but hey presto, that light coloured zone matches the position (and the shape somewhat) of the impact viewed from the rear. What a coincidence.


1. For a start, I don't think they are even close to be in relative similar positions.
2. Secondly your crack looks to be too big and not the right shape.
3. And thirdly and most importantly, from Altgens' position, the left side of you crack is bordered by the mirror and the bottom of the crack is bordered by the top of Kennedy's shoulder.
4 Which fourthly means that your "crack" is simply a white object behind.
