The physics of "back and to the left"

[Jerry Organ]

The more resistance on impact, such as occipital bone, the greater the force transfered to the head Alvarez completely ignores this force by using a melon

The bullet struck above the occipital bone. It entered at the so-called "occipital region", but in the rear part of the right parietal bone.



This drove the upper part of the skull forward and caused the explosion of the head exactly where we would expect to see it.

 Maybe.It's really irrelevant The question is how much bone absorbed energy from the bullet and whether Alvarez took that into account

[Chris Bristow]

The jet-effect is basic physics.  It has been duplicated in real life by, among others, Chad Zimmerman with his turkey shoot:

If the bullet impacted just one inch to the right of where it is hanging from, then the turkey would start rotating counter clockwise. It looks very much like the bullet is entering on the far side of the turkey. It looks like the rotation we see has nothing to do with jet effect.
We also see it swing slightly left in the direction of the bullet path and then it swings back slightly to the right. Of course it does that because it is being suspended from directly above.  There is nothing in that test that is worth anything. Claiming the counterclockwise rotation is a jet effect is gas lighting.
