Did not, you moron.
Did so. You claimed that the back wound was 2 inches right of center and the distance from the back to neck was 6.5 inches, correct? I put the wound 2 inches right of the spine and extended a line thru the spine and out the throat. The angle for that happened to be 12 degrees. I admit that I shouldn't have extended the line to the chest cavity but this was merely to show you the path of the MB thru JFK's spine. You seem to be confusing this with the pitch angle from the 6th floor of the TSBD. I was giving you the benefit of the doubt and setting that at 9 degrees, when the official angle was actually estimated to be 7 degrees.
Here's YOUR final solution:
Looks like the bullet smashes thru C7 to me (just above T1 as depicted in the graphic AND the x-ray)
