RS-
Almost all the Parkland witnesses placed a large-appearing wound in the lower rear right of JFKs head. You've seen the photos, films.
I don't see how a shot from the front, but then exiting the lower rear right of JFK's head, would spew matter to JFK's left.
TBH, the comments of Parkland witnesses are puzzling.
I am open to the possibility of a shot from the GK, more from the side than the front. But the surviving x-rays do not reveal such a shot.
In general, I think the cadence of the shots---"bang....bang-bang"---is more indicative of second gunsel. Gov. JBG shot at Z-295 and JFK at Z-313. Both from behind, and too rapidly to have been done by a shooter armed with a single-shot per bolt-action rifle.
The perps may have been Alpha 66, JMWave-attached, or G2, likely independent and low-level perps acting on their own.
Just IMHO.
A side notion: Is the Walker shooting the real Rosetta Stone of the JFKA?
My take is LHO was involved in the Walker shooting, and someone gave him a ride. Then he goes to New Orleans, but so what?
It is back in Dallas when he is involved in JFKA---with the same guys who went on the Walker shooting?
