Clint Hill's Moving "Rear" Head Wound

Graphic Language.
Sometimes he moves his hands forward from the wound, sometimes backward, sometimes the wound is to the front, usually it's to the back. Sometimes it's an exit, sometimes an entry. But while the placement of his hands changes over the years, everything else he describes stays exactly the same.
Palamara's made a lot of videos charting how Hill changed his story on why the protective detail weren't on and around the car. As with Groden's OJ Simpson testimony, this shows that Hill was willing to lie/has a record of it.
In my view he's casting doubt on his earlier story but putting his hands in different places for the same description. Of course he was under great pressure to do so and had great incentive, he kept publishing new books. I suspect McCubbin his late-life wife and publishing partner was also his handler.
