Reports say bullet fragments were found on the inside dash - though questioning, "from which bullet," would surely begin another discussion... Some say a bullet left a pencil-wide hole in the windshield...
And certainly, no one should expect to find fragments on the outside, if there were any, unless they were found along the road, or in the windshield wiper cavity...
That's my take on it...
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.
