We've been having an ongoing discussion about the physics of the Kennedy headshot

There's an argument that Kennedy's movements after the headshot proves a shot from the front. This was the summation of Kevin Costner's argument in the movie JFK.

**The sixth and fatal shot—frame 313—takes Kennedy in the head from the front. This is the key shot. The president going back to his left. Shot from the front and right. Totally inconsistent with the shot from the depository. Again... back and to the left… back and to the left… back and to the left… back and to the left.**

The problem with this argument is bullets don't work this way. They are counterintuitive.

They have a lot of kinetic energy so they could PIERCE right through things. They don't have very much momentum so they really can't push things much

So here's another video of yahoos shooting things so we can see this principle. I recommend turning down the sound.

There's tons and tons of videos that demonstrate the physics of a gunshot, but it's hard to tell if the target freestanding or held in place in any way.

This one is clear that the target is not constrained and it's one we can all imagine moving with just our hand. It's a giant rubber band ball that weighs about 20 lb. JFK was 170 lb and his body went back pretty fast after the headshot. Given that ....before you watch the video:

Ask yourself if you shot a rubber band ball with a pistol what do you expect it to do?

How far do you expect the ball to go flying backwards? It's something we could easily shove several feet with a simple push. And once it gets going you'd expect it to roll. So what do you expect to happen?

Does the ball move more or less than you expected?

My wife has something going on from like a Friday to Sunday so where near Albany where she needs me to drive her up and then pick her up and drive her home. So I figured this would be a good time to go up to lake George which I used to visit as a kid.

If you had just the weekend and were doing solo travel what would you do? I think my plan is to not even get a room until I'm up there. I definitely want to get on the water so any cruises people can recommend. And I like the idea of lakeside dining.

Lunch at one of the Sagamore restaurants? What's a good mountaintop view. We used to stay in Bolton Landing.

This is a topic we have discussed before and it's something that is still hard to understand and that is how far do we expect a bullet to push the object it hits.

The argument for a shot from the grassy knoll was Kennedy was pushed back and to the left. Kennedy weighed about 170 lbs

At about 11 minutes into this video, the dude shoots a 65 lb block of lead with a .308 bullet that has about 25% more momentum than a Carcano bullet

https://youtu.be/uvq4\_Nm7gPA?t=670

The 65 pound lead block does not move backwards. And it is absorbing all the momentum of the bullet. He eventually moves up to massive elephant guns that do move the 65 lb block.

Explanation

When a bullet is shot and it is motion it has a few properties of motion including momentum and kinetic energy

>Momentum tells you how hard it is to stop something, while kinetic energy tells you how much work that moving object can do.

Momentum is the thing that pushes you back. Kinetic energy is the thing that blasts the hole in you.

kinetic energy

The blasting of a bullet hole through a door is an example of work being done. Kinetic energy can become other forms of energy like heat, sound and strain energy. When the strain energy is too great, you will get a permanent deformation of the object.

Momentum.

If I put my hands on your chest I can shove you backwards. But I'm not going to cause holes in you. That's because there's enough momentum in the shove for you to move back, but not enough kinetic energy for me to blast you open.

Looking for new to me music

Critics of the Warren Commission like to point out discrepancies or anomalies in the case to make the claim there could not be a single shooter.

​

But they do not examine all the anamolies and discrepancies of the case they are making.

​

They don't put their claims together in a way that could match the evidence.

​

And when you are serious about the evidence, you find they have many Magic Moments of their own to deal with.

​

The term Magic Bullet was a fantastic bit of propaganda, but it was never a good faith argument. It was never interested representing what the Warren Commission said about the single bullet.

​

Off the top my head here are some Magic Moments

​

#Magic Moment #1 More shots than the witnesses heard.

​

About 74% to 80% of these earwitnesses reported hearing exactly three shots.

​

The next highest number was only 2.

​

Only a very small number like under 5% heard 1 shot or 4 shots or more than 4 shots

​

#Magic Moment #2 Same location for all shots

​

Even fewer claim shots came from separate locations. I am not sure how many researchers appreciate this. But only 4 witnesses heard shots from more than one location according to the HSCA. Other counts out this at 8.

This is one of the few facts that gets over 90% agreement

​

#Magic Moment #3 Many more magic bullets

​

-If Kennedy was not shot straight through, we have a bullet that penetrated his back and just stopped and was not found in his body or in the car. We also have a bullet that penetrated his neck and just stopped and was not found in his body or the car. And This bullet arrived within the same fraction of the second as the back bullet when Kennedy was behind the sign in nearly in line with the back shot.

​

-We have a bullet that goes into Connally's thigh and doesn't even go as deep as the bone. It can't be a direct shot. Tests showed a direct shot to Connally's wrist would cause much more damage to the bone. Connally said he was hit once. Even leaving out JFK it seems apparent all commonly swollen's wounds come from a single shot. Where's the magic bullet That causes all of Connolly's wounds AND misses Kennedy? What shot could achieve this.

​

​

#Magic Moment #4 The grassy knoll shot that stops mid brain and disappears

​

There is no exit wound on the left side of the of Kennedy's head. There is no damage to the left side of Kennedy's brain. How can a bullet from the grassy Knoll have done this? There have been many Magic bullets proposed to explain this. Frangible bullets, exploding bullets, etc

​

​

#Magic Moment #5 Coordinated head shots

​

The Zapruder film only shows one shot to the Head. So this becomes a severe time restriction for a second shot to the Head.

In frame 312 Kennedy's head is intact. In 313 we see the explosion. There's no other time we see a wound to the head. Which means this is constrained to 1/18 of a second. Or 55 milliseconds.

​

People have claimed that the plan was a coordinated shot to the head. So that the bullets would hit Kennedy at the same time. This kind of sounds maybe like it could happen but once you look into it, this is an absolutely a magic moment.

​

You would have at least two separate people---more if you believe in the triangulation of crossfire theory----shooting separate guns from different distances and timing the shots perfectly.

​

​

The reality of something like this rules it out as a possibility. How can you coordinate the shots? If you're using the same weapon with the same bullets you still have to adjust for the difference in flight speed. The closer shooter would have to pull the trigger in instant slower than the first shooter. But wouldn't have no way of actually knowing the reaction time of the first shooter. You realize there's no way to actually plan for this. There's no signaling system that would work. There's no adjusting gunpowder amounts. The second shooter would never have perfect enough information. The idea of the umbrella man signaling with his umbrella would never work. Ok Google. No way to be able to see him and to be eyes on your target.

​

​

#Magic Moment #5a. Even more magically coordinated head shots. Shots to the same location.

​

Some people claim the second shot was aimed to exit wound of the frontal shot.

​

Cyril Wecht claimed the second shot is not visible in the film because the second shot entered the already fractured area and created overlapping wound tracks that were mistaken for a single wound.

​

He also entertained the idea of a magical frangible bullet for a while.

​

What other Magic Moments are there?

I have a road trip coming up and some audible credits.

​

Unfortunately some of the classic books are not available on audiobook. Anyone use PDF to speech software? What would you recommend?

​

I am kind of most interested right now in the history of the debate.

​

Apparently David Lifton 's book is a good intro to the critics. And I would like to get six seconds in Dallas PDF and convert to audio

​

I've been trying to find the link for their high contrast photo of frame 313, it removes all other detail except white or black. And it shows a line of fragments going above Kennedy's heads.

​

I'm also trying to find the actual report. They did a written report and I know that the sixth floor museum has a physical copy you can read, but I don't think it's anywhere online that I can find.

Was in a store today with a line and the guy in front of me looked familiar, but not specifically.

It was more than I thought. I had seen a few people who looked like him. But it was him. It's just he's more grown up now. My wife saw him again as he exited the store and realized it was him.

Also the new show on Netflix the Borroughs is good. Lester Freamon is in it
