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.
Mr. Dulles. As far as the car is concerned from the back to the front?
Mr. Frazier. Yes, sir.
Mr. Dulles. Not from outside against the glass—from the front against the glass.
Mr. Frazier. That is right.
Mr. Specter. Was a comparison made of the lead residues on the inside of the windshield with any of the bullet fragments recovered about which you have heretofore testified?
Mr. Frazier. Yes. They were compared with the bullet fragment found on the front seat, which in turn was compared with Commission 399. The lead was found to be similar in composition. However, that examination in detail was made by a spectrographer, Special Agent John F. Gallagher.
Mr. Specter. Was that examination made in the regular course of examining procedures by the FBI?
