JFK Assassination Discussion & Debate / Re: Fourth Edition of "Forensic Science and President Kennedy's Head Wounds"
« Last post by Stewart Fillmore on Yesterday at 02:13:02 AM »Elements of a shooting can be replicated individually to demonstrate what is possible. For example the Haag forensic team demonstrated by firing a Carcano round through ballistic gel that such a round tends to yaw upon exiting soft tissue. That doesn't prove the bullet that left JFK's throat yawed upon exiting but combined with the fact that the entry wound on JBC's back was elongated, it seems highly likely that is what happened. Likewise, an Australian documentary team used animal carcasses to simulate JFK's and JBC's bodies. It took them a number of tries before they got the bullet to pass through the simulated soft tissue and bone that the single bullet would have but when they did, the bullet ended up looking very similar to CE399. The nose was intact and there was flattening at the base. The bullet was bent more than CE399 but it is unreasonable to expect such an experiment could perfectly replicate CE399.
Indeed the Carcano bullet tends to yaw upon exiting. I’ve recreated it with ballistic dummies with pigskin wrapped around the neck while wearing a dress shirt, necktie and suit coat. In fact most times (3 of 4 in my testing) made full side on entries in the Connally dummy. But Connally’s jacket didn’t reflect a side on entry but a 1/2 by 3/8 inch hole (which was compromised as evidence because it was dry cleaned before being properly analyzed. Haag incorrectly said that Connally had a full side on wound. Dr Shaw described the wound as elliptical and 1.5 cm in its greatest diameter. He later told the HSCA he felt the wound was from a tangential entry rather than a yawing bullet. But I agree, an elongated wound could indicate the bullet had been knocked off a stable trajectory (ie going thru JFK first). However, Connally said consistently until the day he died that he was turning as he was hit. I know from many firearms training sessions in the FBI using turning targets that a stable bullet striking a rotating target will leave an elongated entry. So I did tests on the range shooting into the Connally target while it was rotated from its right to left. The results were an elongated entry approximately 1.5 cm wide.
Regarding the Australian test, if you’re talking about the one done for Unsolved History (JFK Beyond the Magic Bullet) by Alex Krstic, they didn’t shoot animals (the Edgewood testing did) but ballistic dummies with bones embedded in the Connally dummy. They set it up following the SBT parameters fairly accurately. Yet despite an exit well below the throat in JFK’s chest. They recovered the bullet and its nose was deformed and the shaft of the bullet was bent. Despite both these discrepancies, the narrator stated the single bullet theory had been confirmed.
Interestingly when I first started my testing, I tried simply to replicate the 1/2 inch overlapping vertical slits in the dress that J Edgar Hoover told the WC was typical of a bullet exiting cloth. I also faithfully set up my dummy (with the same ballistic gel covered around the neck with pigskin and wearing a suit) by the WC parameters. My aim point was 5 3/8 inches below the top of the suit collar with the jacket bunched approximately 2 inches and the dummy sitting normally upright. With a 17 degree shot to that point, I not only got a round exit hole but an exit in the chest 2 1/2 inches below the throat. To get the bullet to exit near the shirt collar, it took a near horizontal shot aimed at the suit collar. I ran it 19 times and got 19 round exit holes—not a single vertical slit. But the trajectory discrepancy really intrigued me and led to the remainder of my SBT testing.
