Mr. FRAZIER. The hole in the front of the shirt does not have the round characteristic shape caused by a round bullet entering cloth. It is an irregular slit. It could have been caused by a round bullet, however, since the cloth could have torn in a long slitlike way as the bullet passed through it. But that is not specifically characteristic of a bullethole to the extent that you could say it was to the exclusion of being a piece of bone or some other type of projectile.
Mr. SPECTER. Have you now described all of the characteristics of the front of the shirt holes which you consider to be important?
Mr. DULLES. Could I ask one question there. If the bullet, after entering, hit something that made it tumble or change, would that account for this change in the appearance of the exit through the shirt?
Mr. FRAZIER. I think not. In my opinion it would not have been necessary, if I may put it that way, for the bullet to have turned sideways or partially sideways in order to make an elongated hole.
Mr. FRAZIER. I think the effect in the front of the shirt is due more to the strength of the material being more in the horizontal rather than the vertical direction which caused the cloth to tear vertically rather than due to a change in the shape or size of the bullet or projectile.
Mr. DULLES. Or possibly the velocity of the bullet at that place, would that have anything to do with it?
Mr. FRAZIER. I think the hole would not have been affected unless it was a very large change in velocity.
The CHAIRMAN. Mr. Frazier, I notice that the front of the shirt immediately around the hole you have just been describing and in fact on much of the front of the shirt is bloodsoaked. Would that, with the other evidences you have seen there indicate to you as an expert that this was the exit of the bullet that had entered in the back of the coat as you have described it?
Mr. FRAZIER. The presence of the blood would have in my opinion no value for determining which was entrance or exit, because I have seen entrance wounds which bleed extensively and exit wounds which bleed not at all and vice versa. It depends entirely on the type of bullet which strikes, whether or not it mutilates itself in the body, and probably more importantly it depends on the position of the person who is shot after the shooting occurs as to where the blood will be located on the garments.
