My post says a shot from the front causing the back/left motion
Ok, let's explore your premise. You believe this was a conspiracy and there were 2 near simultaneous head shots that you believe came from the
back and the front:
1) Do you consider the knoll shot to be the "shot from the front" or do you doubt the knoll shooter existed? If so, then where was the frontal shot taken from?
2) What damage did the shot from the front inflict on JFK and was it a frangible bullet (unlike a FMJ bullet such as CE399)?
3) Did the shot from the front blow out JFK's right temple or did it blow out a fist-sized hole at JFK's right occipital, or both?
4 ) What effect did the shot from behind have on JFK's body and what damage did it inflict on JFK?
5) Did the shot from the back blow out JFK's right temple or blow out a fist-sized hole at JFK's right occipital, or both?
What's your guesswork?
The only shot from behind that hit the target was the magic bullet with the impossible trajectory, that Oswald didn't take.
Guesswork
There may have been another simultaneous shot from behind taken from the Dal-Tex building from the same shooter that struck JFK in the back and out his throat, but there is no evidence for it. The right temple skull flap notwithstanding. Otherwise, there is no trajectory from the 6th floor of the TSBD, into JFK's back and out his throat. This is not guesswork, it's simple geometry.
PS The near simultaneousness of the shots at the Turkey Shoot Point (where the limo slowed down to) was by design, so that 2 or more shots sound like a single shot + echoes.
Fantasy
You just need to apply some logic and critical thinking here. If you are convinced there were 2 or more shooters then you believe this was a conspiracy. If so, then it was a coup d'etat. Every good coup needs a patsy. Oswald was it. He had to be portrayed as a LN and the ONLY shooter. How do you accomplish that with multiple shooters set up in a crossfire? It is imperative that no one suspects there was more than Oswald taking shots at JFK. The ONLY way to pull that off is to have a Turkey Shoot Point where several near simultaneous shots sound like 1 shot + echoes.
You do the math Mr. Fantasy, I didn't invent this concept, I'm just relaying it. Otherwise, you must be a CT (Coincidence Theorist) to think that multiple shooters set up in a crossfire just happen to take their shots a fraction of a second apart.
