Debunking the "Jet Effect"?

[Andrew Mason]

Just for laughs - Andrew, do you think the image above shows matter being expelled out of the front of JFK's head?.

From the front half of his head?  Yes.
From the front surface of the head?  No

What matters is the direction of the matter exploding from the head exit wound at the moment it separates from the body. That matter spewed over a wide area that included the inside the car, on either side of the car, on the windshield and over onto the hood of the limo. 

The resulting kick from that explosive ejection of that matter will be equal in magnitude and opposite in direction to the vector sum of the momenta of all ejected particles at the moment they separated from the body.

I'm not even going to ask what this means.
So, just to be clear, you're saying the expulsion of matter highlighted below is coming from the front half of JFK's head.
It's a yes/no thing.

That is what I said.  But I also said that what matters is the direction of the ejected matter.   The point on the head from which it ejected does not affect the direction of the recoil.

Of all the truly ridiculous things you've posted in your time on this forum, this is the winner.
It's on the record.
It can't be taken back.
It's great knowing that you're going to double-down on this as well.



Do you still stand by your statement that this "jet" of material is coming from the "front half of his head"?

If you divide the head into a forward and rear section by a line from the ear to ear, it appears to me that the exit wound in the scalp is forward of that line.   

I don't know why you think that matters.  What matters is the direction that the particles of expelled matter have when they are being forced outward from the head by the pressure built up inside the skull. The recoil momentum imparted to the head/body is the vector sum of the momenta of all those particles of matter but opposite in direction. 

If you think that is ridiculous, perhaps you can explain how your understanding of high school physics causes you to reach a different conclusion.

Does deceleration of the limousine, moments before & during the fatal headshot, disprove the so called "Jet Effect" & explains why the President & everyone else in the vehicle moved slightly forward? In this video by Gil Jesus, between frames 312 & 313 specifically, we can see this taking place. Thoughts?

Also this debunking of Lattimer and Alvarez -

The second video debunks nothing. The first is simply wrong: the apparent relative motion caused by the limo's deceleration is over with by frame z310. Further, if you toggle back and forth between frames 312 and 313, you'll find that JFK's head moves quite a bit relative to his wife's, the Connallys' and the SS agents in the front seat. If the motion was caused by the deceleration of the car, it would have affected all of them about the same.

Aaaahhh...this is such a treat.
Thanks to having dealt with your issues elsewhere I knew you couldn't accept the error of your ways.
I'm just going to savour watching you dig this hole for yourself.
But first I'm going to help you out otherwise we'll get nowhere.
So, let's start off with a basic anatomy lesson.
In fact, this is as basic as it gets.
Below is a picture of JFK's head in profile.
I've eyeballed a centre-line for his head (the yellow line). It doesn't have to be exact, it's just to get a general idea.
To the left I've written the word "BACK".
To the right I've written the word "FRONT".
This is to demonstrate where the front half of his head is and where the back half of his head is.



I want you to have another look at the image below, with the anatomy lesson in mind, and tell me again - do you still think the "jet" is coming from the front half of his head?

Take your time 

Your line is arbitrary. The back half of the skull appears to me to be intact.  Again, why do you think it matters?  Take your time to review your high school physics.
