I don't know why I overlooked this before but Oswald was not firing downward at 60 to 70 degrees at the time the single bullet struck. At Z225, the closest exhibit to the time the single bullet struck, the angle to the rifle was 20 degrees. That would mean the slope on JFK's back would only have to be greater than 20 degrees to create an upward angle of entry. Since the area above the shoulder blades already has a natural slope to it even whan a person is sitting or standing perfectly upright. Due to JFK's bad back, he would tend to hunch his back slightly to relieve pressure on his spine. He would not have to be leaning or hunching over much to create a greater than 20 degree slope in his back.

All of your beliefs strain credulity.

You guys scoff at the SBT as requiring a magic bullet, then try and tell us there was a magic shooter who disappeared into thin air after firing the kill shot from behind the wooden fence.

If you look carefully at a good copy of Altgens 6, you'll see the complete right edge of the rearview mirror, unbroken, along the left side of the alleged "windshield damage." In fact, the right side of the "damage" is bounded by the mirror on the left and by JFK's shoulder on along the bottom. The only way that could happen is if the mirror and JFK were in the foreground with respect to the "windshield damage." Therefore, whatever the alleged damage is, it's in the background behind the mirror. It's not on the windshield at all. This destroys the idea that the windshield damage occurred before frame 255.
