Mr. Frazier. Yes.
Mr. Eisenberg. Are all the marks shown in both photographs identical?
Mr. Frazier. No.
Mr. Eisenberg. And could you go into detail on a mark which is not identical to explain why you would get such a result?
Mr. Frazier. Well, for instance, between what I have drawn here as circle 4 and circle 5, there is a slanting line from the upper left to the lower right on C-6. This line shows as a white line in the photograph.
On the other side there is a rough, very rough ridge which runs through there, having an entirely different appearance from the relatively sharp line on C-6. The significant part of that mark is the groove in between, rather than the sharp edge of the mark, because the sharp corner could be affected by the hardness of the metal or the irregular surface of the primer and the amount of pressure exerted against it, pressing it back against the face of the bolt, at the time the cartridges were fired. So that you would never expect all the marks on one cartridge case to be identical with all the marks on the other cartridge case.
In fact, you would expect many differences. But the comparison is made on the overall pattern, contour, and nature of the marks that are present.
Mr. Eisenberg. Off the record.
(Discussion off the record.)
Mr. Eisenberg. Back on the record.
