The true trajectory of the bullet has it exiting from just to the right of Jfk's midline and then traveling to the point entry on JBC'S back, which was most definitely to the right of his midline.
I am just pointing out that it is only true if you use ITEK's maximum distance that JBC was left of JFK's midline and add at least 3 inches. And you still have a problem fitting that to the witness evidence that JFK reacted to the first shot. An alternative explanation that does not conflict with consistent and well corroborated witness observations is available. It has the first bullet going to JBC's left side.
It is interesting, by the way that Dr. Olivier did not rule out JBC being hit in the back by a pristine bullet.
