Are you having comprehension problems, if so let me repeat my comment.
What happens after the initial impact on a medically proven one point entry, is essentially worthless in solving the crime.
Yes John, I am having problems comprehending what you're posting but I don't think that's on me.
I still haven't got a clue what the above comment has to do with the Jet Effect.
I'm not going to ask for you to clarify it again as it's getting nowhere.
What happens after the initial impact is worthless in solving the crime??
If any other forum member can help me understand what this comment has to do with the Jet Effect, please help.
And I already stated earlier with examples of Real World reproductions of what happened after, that explains why Kennedy went back and to the left.
But let me further clarify, Kennedy was shot from behind, the majority of the internal pressure escaped through the front right side of Kennedy's head and therefore the reaction was in the exact opposite direction of back and to the left.

"...the majority of the internal pressure escaped through the front right side of Kennedy's head..."What evidence do you have for this?
Especially when you are showing an image that clearly demonstrates the pressure escaped through the top of his head.
Now you may theorize that a second undetected bullet which left no damage came from the front right and that is your right, but you'd be wrong.

WTF are you on about?
