Mr. SPECTER - Will you state your name again for the record, please?
Mr. FRAZIER - Robert A. Frazier.
Mr. SPECTER - Mr. Frazier, you have appeared heretofore to testify about certain tests which you have conducted, but at this phase of the record, will you state briefly your occupation and your specialty, please?
Mr. FRAZIER - I am a special agent assigned to the FBI laboratory, the firearms identification unit in Washington, D.C., where I make examinations of bullets, cartridges, gunpowder tests, bullet holes, examinations of clothing, and other similar types of examinations.
...
Mr. SPECTER - Did you have occasion then to examine the windshield of the Presidential limousine?
Mr. FRAZIER - Yes; I did.
Mr. SPECTER - What did that examination disclose?
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.
Mr. DULLES - And the outside surface was the surface away from where the occupants were sitting?
Mr. FRAZIER - That is correct; yes.
Mr. DULLES - And the inside surface was the surface nearest the occupants?
Mr. FRAZIER - Yes.
Mr. SPECTER - What do those characteristics indicate as to which side of the windshield was struck?
Mr. FRAZIER - It indicates that it could only have been struck on the inside surface. It could not have been struck on the outside surface because of the manner in which the glass broke and further because of the lead residue on the inside surface. The cracks appear in the outer layer of the glass because the glass is bent outward at the time of impact which stretches the outer layer of the glass to the point where these small radial or wagon spoke-wagon wheel spoke-type cracks appear on the outer surface.
Mr. DULLES - So the pressure must have come from the inside and not from the outside against the glass?
Mr. FRAZIER - Yes, sir; that is correct.
