Mr. Eisenberg. Did you notice, Mr. Frazier, in your examination of targets and so forth, whether there was any marked degree of yaw or tumbling by the bullets?
Mr. Frazier. No evidence at all of tumbling or yaw.
Mr. Eisenberg. In your opinion, would the firing of 60 shots materially affect the microscopic characteristics of Exhibit 139?
Mr. Frazier. It would change them, if not completely, practically completely.
Mr. Eisenberg. Mr. Frazier, some witnesses to the assassination have stated that they heard more than three shots. Can you think of any reason why they might have come to that conclusion—in terms of acoustical properties of high-velocity bullets?
Mr. Frazier. They could very readily have heard other sounds which could be confused with shots. It is apparent—it is obvious with any weapon in which the bullet travels faster than the speed of sound, which is 1,127, approximately, feet per second, the bullet itself will cause a shock wave or a sound wave, and a person standing in front of that weapon will hear the report of the bullet passing and then subsequently the sound will reach them of the cartridge explosion, which could very easily be confused with two shots. There will be the crack of the bullet going by, overhead or in the vicinity, and then the sound of the shot.
So that you would hear for three shots actually six reports, which could have caused some confusion.
Mr. Eisenberg. Mr. Frazier, I now hand you a bullet in a pill box which is marked Q-188. I ask you whether you are familiar with this bullet.
I would like to state for the record that this bullet was found in the Walker residence after the attempted assassination of General Walker.
Mr. McCloy. As far as you know, we have no proof of that yet?
