Mr. SHANEYFELT. On most occasions, Mr. Gauthier of the FBI was present, I was present, Mr. Malley of the FBI was present. Inspector Kelley from Secret Service, and Mr. John Howlett from Secret Service. Representatives of the Commission were always present--normally Mr. Redlich, Mr. Specter, or Mr. Eisenberg were present. On several occasions Mr. Ball and Mr. Belin were present. Mr. Rankin was present on some occasions. I believe Mr. McCloy was present on one occasion. Various representatives of the Commission were present. Mr. SPECTER. And how long did those analysis sessions ordinarily last? Mr. SHANEYFELT. They would normally last most of the day, about all day. Mr. SPECTER. And what would be done during the course of those analytical sessions? Mr. SHANEYFELT. In each case we would take the film and run it through regular speed, slow motion, we would stop it on individual frames and study it frame by frame, trying to see in the photographs anything that would give any indication of a shot hitting its mark, a reaction of the President, a reaction of Mr. Connally or Mrs. Connally, reaction of the Secret Service agents, reaction of people in the crowd, relating it to all the facts that we felt were important. When we obtained the slides from Life magazine, we went through those very thoroughly, because they gave so much more detail and were so much clearer and analyzed again all these things about the reaction of the President and Mr. Connally, trying to ascertain where he was reacting--whether either one was reacting to being hit. Of course the only shot that is readily apparent in any of the films, and it appears in the Zapruder, the Nix, and the Muchmore films, is the shot that hit the President in the head. Mr. SPECTER. Why do you say that is readily apparent? Mr. SHANEYFELT. Because on the film there is practically an explosion of his head and this is obviously the shot that hit the President in the head. It is very apparent from the photograph. Mr. SPECTER. Now, were any others present at any time, such as witnesses who appeared before the Commission, during the analysis sessions on these films and slides? Mr. SHANEYFELT. Yes. On April 14, representatives of the Commission, FBI, and doctors--Dr. Hume of the Navy, who is at Bethesda, Commander Boswell from the U.S. Navy Medical School at Bethesda, Colonel Finck, Chief of the Wound Ballistics Pathology of the Armed Forces Institute of Pathology. Mr. SPECTER. Are those the autopsy surgeons? Mr. SHANEYFELT. Yes; that is my understanding. Dr. Olivier, from Edgewood Arsenal, Dr. Light, from Edgewood Arsenal, were present also with Dr. Humes and the others, on April 14. Mr. SPECTER. Did any individuals who were present at the motorcade itself ever have an opportunity to view the films and slides?
