"The Kennedy Assassination was the crime of the century. Nearly fifty years have passed since that tragic November day, yet a steady stream of conspiracy and theoretical books still abound.
"Head Shot" scientifically resolves one of the most enduring mysteries in US nation's history. Drawing on a fifteen-year career as an experimental physicist for the US Navy, Dr G.Paul Chambers has produced the first work on the subject to use the laws of physics and motion to :
- identify the real murder weapon
- prove the locations of the assassins
- demonstrate a conspiracy beyond any doubt."

Conspiracy book.
From back cover:
"The evidence is chilling. The photographic proof is graphic and disturbing. The facts can no longer be denied. HIGH TREASON challenges everything we have been told about the motives behind President Kennedy's murder. For there is now convincing evidence that, from the fateful day in Dallas through two decades of speculation, a massive conspiracy ordered JFK's demise and sabotaged the investigation that followed. It is a cover-up that continues to this day.
Robert J.Groden, coauthor of "JFK:The Case for Conspiracy",and Harrison Edward Livingston reveal the dark heart of a deadly conspiracy".

Conspiracy book.
From back cover:
"Was primary evidence used to support the lone gunman theory faked? Do these forgeries prove a massive conspiracy? If so, how was this done and who did it?
What part did manufactured evidence play in the cover-up? And what is the connection between tyhe Warren Commission's conclusions and other national tragedies of the 1960s and '70s?
In this second volume of his monumental study of President Kennedy's Assassination, Harrison Edward Livingstone takes his courageous investigation where no researcher has gone before. He answers these questions and others while offering astute analysis of the political and historical forces that mandated Kennedy's murder."

In 1976, the House Select Committee on Assassinations undertook reinvestigations of the murders of John F. Kennedy and Martin Luther King, Jr.
In 1979, a single Report and twelve volumes of appendices on each assassination were published by the Congress. In the JFK case, the HSCA found that there was a "probable conspiracy," though it was unable to determine the nature of that conspiracy or its other participants (besides Oswald). This finding was based in part on acoustics evidence from a tape purported to record the shots, but was also based on other evidence including an investigation of Ruby's underworld connections. The acoustics evidence was disputed by a panel of scientists, but that "debunking" has itself come under attack recently.

Volume I, the first of five volumes of hearings of the HSCA, consists of transcripts of the HSCA proceedings of September 6 through 8, 1978.
The opening day of hearings got underway with a statement by Representative Richardson Preyer, followed by the testimony of Mr. and Mrs. John Connally. The Governor of Texas in 1963, John Connally had been involved in preparations for the fated motorcade trip. He was also wounded in the shooting in Dealey Plaza.
The second day of testimony related to the medical evidence and analysis in the case. Much of this was presented by Dr. Michael Baden, head of the HSCA's nine-member Medical Panel. This day also saw the testimony of Capt. James J. Humes, the lead prosector at the autopsy of President Kennedy. Humes publicly retracted the autopsy report's placement of the fatal entry wound, which the Medical Panel determined was 4 inches away from the originally-noted spot. In 1992 for the Journal of the American Medical Association, and again in 1996 before the Assassinations Record Review Board, Humes retracted this retraction. The final medical witness on Sept. 7 was Dr. Cyril Wecht, the lone dissenter on the Medical Panel.
The third day, Sept. 8, continued the medical testimony and presented the findings of the Firearms Panel, concerned with the ballistics evidence. The final witness was Dr. Vincent Guinn, who performed Neutron Activation Analysis (NAA) on bullet fragments to determine whether they came from the same bullet.

Volume II of the HSCA hearings volumes consists of the proceedings of Sept. 11 through 15. 1978.
The transcripts of these days includes testimony about acoustics evidence, trajectory analyses, the testimony of accused assassin Lee Harvey Oswald's wife Marina, photographic analysis, and testimony concerning Yuri Nosenko, a Soviet defector.
The testimony of Sept. 11 was concerned with analysis of an audiotape purported to have captured the shooting in Dealey Plaza. It was recorded on a Dallas Police radio channel due to a stuck-open microphone on a police motorcycle. The acoustic analysis showed at least 4 shots, with one of these coming from the "Grassy Knoll." This conclusion was subsequently disputed by a panel appointed by the National Academy of Sciences, but that rebuttal itself has been called into question by a recent peer-review article by D.B. Thomas presented in Science and Justice in 2001.
The Sept. 12 proceedings began with the testimony of Calvin McCamy concerning the Zapruder film, and what a detailed analysis showed about when shots may have been fired. This was followed by a trajectory analysis presented by Thomas Canning.
The next day of proceedings, and part of the following, was taken by the testimony of Marina Oswald Porter, former wife of Lee Harvey Oswald. Following that was testimony by members of the Photographic Panel, who examined the famous "Oswald backyard photos" among other photographic evidence relevant to the assassination.
The photographic testimony continued into Sept. 15, followed by the testimony of John Hart. Mr Hart discussed the case of Yuri Nosenko, a Soviet officer who defected to the U.S. in early 1964. Nosenko's "bona fides" were a subject of great contention within the CIA, which imprisoned and interrogated Nosenko for a period of three years.

Volume III of the HSCA hearings volumes consists of the proceedings of Sept. 18 through 21, 1978. This included testimony from Cuban officials, the Secret Service, and former members of the Warren Commission.
Following narrative by the HSCA's Chief Counsel G. Robert Blakey, the first witness on Monday, Sept. 18 was Eusebio Azcue Lopez, former Cuban Consul in Mexico City. Azcue reiterated his belief that the person he dealt with in the fall of 1963 was not Lee Harvey Oswald. Azcue was followed by Alfredo Mirabal Diaz, who replaced Azcue as Consul and was also present during the "Oswald" visit.
The Sept. 19 proceedings began with Thomas Kelley, an inspector for the Secret Service, who conducted the Secret Service' investigation into the assassination. Mr. Kelley was followed by Secret Service Chief James Rowley. The following day, testimony was heard from two FBI agents involved in its investigation, James Malley and James Gayle.
Sept. 22's proceedings included the testimony of three Warren Commissioners and its General Counsel: Former President Gerald Ford, John Sherman Cooper, John J. McCloy, and J. Lee Rankin. They were followed by Nicholas Katzenbach, who was Assistant Attorney General at the time of the assassination and had written the famous "Katzenbach memo."

Volume IV contains the proceedings of Sept. 22, 25, and 26, 1978.
 The first day was taken up with the testimony of Richard Helms, former Director of the CIA. Mr. Helms was Deputy Director for Plans at the time of the JFK assassination, and was responsible for responding to requests from the Warren Commission.
The morning of Sept. 25 saw the return of handwriting expert Joseph McNally, photographic expert Sgt. Cecil Kirk, physical anthropologist Dr. Clyde Collins Snow, and photo enhancement expert Dr. Bob Hunt. The afternoon session included the interview of Louie Steven Witt, purported to be the "Umbrella Man" seen in the Zapruder film. Mr. Witt was followed by HSCA staffer Jacqueline Hess, who gave a presentation of the HSCA's analysis regarding the "mysterious deaths" issue.
The following day began with a narrative by Chief Counsel Blakey, and then continued with the testimony of Earl Ruby, brother of Jack Ruby. Mr. Ruby was followed by Capt. Jack Revill of the Dallas Police Department, who was part of the investigative team originally charged with determining how Jack Ruby had entered the police basement where he shot Oswald.

The last of the five Hearings volumes of the HSCA consists of the proceedings of Sept. 27 and 28, 1978, plus an additional day of hearings held on December 29, 1978.
The September testimony was concerned primarily with organized crime. The final day of hearings, held 3 months later, dealt with acoustics evidence.
Sept. 27 was taken up largely by the testimony of Ruby associate Lewis McWillie, who worked in gambling casinos in Havana and Las Vegas. McWillie was followed by Jose Aleman, a Cuban exile who was the son of a former Cuban minister of education.
The following day, Sept. 28, began with the testimony of organized crime boss Santos Trafficante, followed by a presentation by Ralph Salerno, the Committee's consultant on organized crime. After Salerno the Committee questioned Judge Burt Griffin, a former Warren Commission staffer who had been involved in the Ruby investigation.
Three months later, on Dec. 29, the Committee heard more testimony on the acoustics evidence which indicated a fourth grassy knoll shot. Witnesses included Professor Mark Weiss and Ernest Aschkenasy, Dallas Police Officer H. B. McLain, and Dr. James Barger. Closing remarks were made by Chief Counsel G. Robert Blakey and Chairman Louis Stokes.

Volume VI of the HSCA's Appendices is the report of the HSCA photographic panel.
The photographic panel examined a much wider variety of photographs and films than did the Warren Commission. It reported on the number and timing of shots via blur (jiggle) analysis of the Zapruder film, and conducted a trajectory analysis as well. It conducted authenticity studies on the Oswald "backyard" photos and the Kennedy autopsy photos, although documents which came to light in the late 1990s cast doubt on the panel's work related to the autopsy photos (see ARRB staff memos). The panel reviewed photos of the "grassy knoll" in order to determine if a gunman was visible in them, and it also examined particular photos to try to settle questions relating to the identity of persons in the photos.
