"Frazier minimized the problem, claiming it wasn't really defective, that "only the adjusting mechanism does not have enough tolerance to bring the crosshair to the point of impact of the bullet," simple to fix by slipping a "shim" under the sight. But, the defect is apparently inherent with that brand, and was there before the hypothetical bump. When, for his experiments, John Lattimer bought four Carcanos "a favorite among European riflemen" and four telescopic sights identical to Oswald's, he found that all four needed shims, and hinted that Oswald had used one. No shim was ever found on or near Oswald's gun."
As I pointed out earlier. the two screws holding the scope mounted onto the receiver are threaded horizontally into the side of C2766's receiver. What i don't seem to be able to make anyone understand is this makes it possible to shim the scope mount for lateral (windage) adjustment but IMPOSSIBLE to shim the scope mount for vertical (elevation) adjustment. The only way to adjust the scope mount vertically is by drilling a new screw hole at one end or the other.
In the case of C2766, it would be necessary to drill a new hole, for the forward end of the scope mount, and to drill it slightly higher than the first hole. This would have the effect of bringing the scope up (or the barrel down - perspective again) and stop the rifle from shooting so high.[/FONT]

Mr. HILL. The right rear portion of his head was missing. It was lying in the rear seat of the car. His brain was exposed. There was blood and bits of brain all over the entire rear portion of the car. Mrs. Kennedy was completely covered with blood. There was so much blood you could not tell if there had been any other wound or not, except for the one large gaping wound in the right rear portion of the head.
