To this day, I'm not sure who took this film, but I know it was in the keeping of the Dallas County prosecutor's office.
But, you can plainly see that the shooter was not shooting downward into Oswald; he was shooting upward into Oswald. And therefore, he could not have made the shot which went downward, as described by the coroner.
The bullet entered at the level of Rib 7. It came to a stop under the skin at the level of Rib 11. The ribs are numbered from superior to inferior. Rib 1 is highest; Rib 12 is lowest. So, that bullet definitely took a downward course. Hence, the Garage Shooter most definitely did not make the shot.
