Cracked windshield and ballistics experts...

[Jake Maxwell]

The outer surface appears to me scratched or chipped...
It seems I recall testimony from 2 or 3 who saw the windshield up close... and they said it appeared to have a hole in it...
This most likely... and very easily... could be verified... with a contemporary expert ballistics analysis...

[Jake Maxwell]

Yes, hard to see that very well...

[Jake Maxwell]

I just chatted with two different Safelite Auto Glass agents, asking if a technician can easily tell if a crack came from the inside or outside of a windshield...
I got the very same reply...: (see screenshot of chat)

“Yes they can!”

[Jake Maxwell]

This one determination of where the crack originated would settle the issue... and answer the question, “Was there another shooter from the front?"
There are ballistics experts who can look at a crack like this and determine from which direction the object came...
Perhaps a technician could make a determination from using only the photo...
If so, it would be interesting to get a response from two or three...
My guess from the location of the crack... if coming from the front... is that “they" were trying to take out Greer... like they took out Oswald... before any incriminating information could be disclosed...
Maybe for Greer it functioned as a warning shot...

 I find it a leap of faith to assume Kellerman mistook fragments hitting the windshield as a flurry of separate shots coming in. Could a person differentiate the timing of a bullet landing from the fragments landing just a few feet ahead? I does not seem like enough time for anyone to think it is two separate shots.
 Then we have Greer who describes the last shots as "almost simultaneous". Both these agents are experienced with weapons yet both are fooled by fragments of a single round?
  There is also lots of corroboration from other witnesses in the follow up car and LBJ's car and other locations. About 25 witnesses said the last shots were in rapid succession,  like automatic fire, almost at the same time and other similar descriptions. They were not in the front seat experiencing the fragments.
 The idea Kellerman mistook fragments for a flurry of separate shots seems like unsupported conjecture.

"The idea Kellerman mistook fragments for a flurry of separate shots seems like unsupported conjecture."

I wouldn't agree that it's unsupported.
The timing Kellerman gives for the "flurry" equates to the head-shot. The bullet fragmented and some of the fragments were powerful enough to crack the reinforced windshield and dent the chrome trim above. He describes it this way -"a flurry of shells come into the car." He does not seem to be describing shots being heard outside the vehicle, he is describing something happening inside the vehicle. In the Z-Film we can see this is the exact moment Kellerman and Greer duck for cover. Personally, I doubt they are ducking from sounds, I think they are ducking from objects smashing into the windshield and chrome trim, something that really happened. Nowhere does Kellerman describe fragments coming into the vehicle.
The timing, the ducking motion of Kellerman and Greer and the actual damage to the vehicle strongly indicate Kellerman is talking about bullet fragments from the head-shot spraying the inside of the limo.
That said, it's just my opinion and not a fact, but I don't think it is "unsupported".

Kellerman actually says "a flurry of rounds CAME INTO the car."
The fact their ducking at the time of the shot is more likely due to the shot/shots than reacting to fragments. Why jump to the conjecture about them reacting to fragments when a round just entered the car? Kellerman said he heard the gross sound of the round hitting JFK's head. I think he described it as a melon being dropped. I am sure that is enough to make anyone duck all by itself. No need to theorize about reacting to fragments.
 But the biggest problem for me is those fragments would hit the windshield a fraction of a second after the head shot.
 The debris that flew up can be measured to over 100mph. The debris that hit the windshield would have been traveling about the same speed. Traveling the 7 feet from JFK to the windshield would take about 1/20th of a second. The debris and fragments would hit the windshield far too quickly for it to be perceived as two separate shots.
 The fact that Greer was looking at JFK when his head exploded and Kellerman said he heard it hit gives us more than enough reason to explain their ducking without invoking the fragments. Or you could say the reacted to both the head shot and the fragments as a single event. But there is no reason to assume they took the fragments to be a separate shot.
