Mr. Eisenberg. How material would you call that defacement?
Mr. Frazier. It is hardly visible unless you look at the base of the bullet and notice it is not round.
Mr. Eisenberg. How far does it affect your examination for purposes of identification?
Mr. Frazier. It had no effect on it at all.
Mr. Eisenberg. Can you explain why?
Mr. Frazier. Because it did not mutilate or distort the original microscopic marks beyond the point where you could recognize the pattern and find the same pattern of marks on one bullet as were present on the other.
Mr. Eisenberg. Did you take a photograph of your comparison of Exhibit 399 with a test bullet?
Mr. Frazier. Yes, sir.
Mr. Eisenberg. This photograph was prepared by you or under your supervision?
Mr. Frazier. Yes, sir.
