Windshield damage came from outside says ChapGPT & GROK... interesting...

[Tom Graves]

Mr. FRAZIER - On the inside surface of the windshield there was a deposit of lead. This deposit was located when you look at the inside surface of the windshield, 13 1/2 inches down from the top, 23 inches from the left-hand side or driver's side of the windshield, and was immediately in front of a small pattern of star-shaped cracks which appeared in the outer layer of the laminated windshield.
Mr. DULLES - What do you mean by the "outer layer of the laminated windshield"?
Mr. FRAZIER - The windshield is composed of two layers with a very thin layer of plastic in between which bonds them together in the form of safety glass. The inside layer of the glass was not broken, but the outside layer immediately on the outside of the lead residue had a very small pattern of cracks and there was a very minute particle of glass missing from the outside surface.

In other words, there was no through-and-through hole in the windshield.

Correct.

[Jake Maxwell]

Correct.

There is other testimony to dispute that....

Actually, there is no sworn testimony to dispute it. The claims made early on and decades later about there being a through and through hole in the windshield are dealt with in a blog entry by Fred Litwin.

The last shot of SSA Hickey's accidental 4 or 5 shot auto burst of his AR15 hit jfk in the head & the remnant slug then veered & cracked the windshield & then must have bounced out into Elm St.

Rynkiewicz,

Here's a saying for you from the 1940s:

"Where do you get off?" as in, "You're stinking up the bus, dude."

So that some of us don't miss the point of it all... Here's the summary again, from ChatGPT:

"In your case:
The image shows a crack with radial lines centered around a small, damaged spot. That strongly suggests an external impact (from a rock or other object)."

Of course, everything posted on the forum deals in probabilities...
So, in fewer words, here's the summary assessment from ChatGPT:

"This image, "strongly suggests an external impact..."
