Mr. SPECTER. What is there, in and of the nature of the smaller wound of exit and larger wound of entrance in the Governor's wrist as contrasted with a smaller wound of entrance and larger wound of exit in 854 and 855, which leads you to conclude that the Governor's wrist was not struck by a pristine bullet? Dr. OLIVIER. Do you want to repeat that question again? Mr. SPECTER. What is there about the wound of entry or exit which led you to think that the Governor's wrist wasn't struck by a pristine bullet? Dr. OLIVIER. Well, he would have had a larger exit wound than entrance wound, which he did not. Mr. SPECTER. And if the velocity of the missile is decreased, how does that effect the nature of the wounds of entry and exit? Dr. OLIVIER. If the velocity is decreased, if the bullet is still stable, he still should have a larger exit wound than an entrance. Now, on the other hand, to get a larger entrance wound and a smaller exit wound, this indicates the bullet probably hit with very much of a yaw. I mean, as this hole appeared in the velocity screen the bullet either tumbling or striking sideways, this would have made a larger entrance wound, lose considerable of its velocity in fracturing the bone, and coming out at a very low velocity, made a smaller hole. Mr. SPECTER. So the crucial factor would be the analysis that the bullet was characterized with yaw at the time it struck? Dr. OLIVIER. Yes. Mr. SPECTER. Causing a larger wound of entry and a smaller wound of exit? Dr. OLIVIER. Yes. Mr. SPECTER. Now is there anything in the---- Dr. OLIVIER. Also at a reduced velocity because if it struck at considerable yaw at a high velocity as it could do if it hit something and deflected, it would have, it could make a larger wound of exit but it would have been even a more severe wound than we had here. It would have been very severe, could even amputate the wrist hitting at high velocity sideways. We have to say this bullet was characterized by an extreme amount of yaw and reduced velocity. How much reduced, I don't know, but considerably reduced. Mr. SPECTER. Does the greater damage, inflicted on the wrist in 854 and 855 than that which was inflicted on Governor Connally's wrist, have any value as indicating whether Governor Connally's wrist was struck by a pristine bullet? Dr. OLIVIER. No; because holding the velocity the same or similar the damage would be greater with a tumbling bullet than a pristine. I think it reflects both instability and reduced velocity. You have to show the two. I mean, the size of the entrance and exit are very important. This shows that the thing was used when it struck. The fact that there was no more damage than was done by a tumbling bullet indicates the bullet at a reduced velocity. You have to put these two things together. Mr. SPECTER. Had Governor Connally's wrist been struck with a pristine bullet without yaw, would more damage have been inflicted---- Dr. OLIVIER. Yes.
