Griffith,
What's the probability that your beloved testers were able to perfectly reenact CE-399's trajectory, angles of incidence, and velocity, etc., not to mention what it did after it exited JFK's throat and started tumbling (which we know from the Haags experiments viewable in "Cold Case JFK" and the oblong entry wound in JBC's back) so as to be able to recreate perfectly the way it was tumbling and twirling when it side-swiped JBC's radial bone?
This is sheer comedy. Let me repeat the fact that in the WC's SBT test, bullets that were merely fired into cotton wadding emerged as deformed or more deformed than CE 399. Plus, are you aware that Connally's back wound showed no indication that it was made by a tumbling bullet, that the mortician said the back wound was about 6 inches below the throat wound, that the rear clothing holes put the back wound well below the throat wound, and that the most sophisticated SBT trajectory analysis ever done proves the SBT is impossible?
This is not to mention the fact that we know that no bullet exited the throat wound because there was no hole in the tie and because the front shirt slits had no fabric missing from them and had no metallic traces around, in addition to the fact that Dr. Carrico and one of the Parkland nurses confirmed that the nurses made the shirt slits.
Are you ever going to face the fact that there was no hole in the tie? Even if we assume a bullet exited the shirt slits, there is no way that bullet could have magically weaved around the body of the tie to nick the left side of the tie knot. Again, there was no hole in the tie, only a small nick near the left edge of the tie knot. This fact alone destroys the SBT.
