The Commission took steps immediately to obtain the necessary staff to fulfill its assignment. J. Lee Rankin, former Solicitor General of the United States, was sworn in as general counsel for the Commission on December 16, 1963. Additional members of the legal staff were selected during the next few weeks. The Commission has been aided by 14 assistant counsel with high professional qualifications, selected by it from widely separated parts of the United States. This staff undertook the work of the Commission with a wealth of legal and investigative experience and a total dedication to the determination of the truth. The Commission has been assisted also by highly qualified personnel from several Federal agencies, assigned to the Commission at its request. This group included lawyers from the Department of Justice, agents of the Internal Revenue Service, a senior historian from the Department of Defense, an editor from the Department of State, and secretarial and administrative staff supplied by the General Services Administration and other agencies.

In addition to the assistance afforded by Federal agencies, the Commission throughout its inquiry had the cooperation of representatives of the city of Dallas and the State of Texas. The attorney general of Texas, Waggoner Carr, aided by two distinguished lawyers of that State, Robert G. Storey of Dallas, retired dean of the Southern Methodist University Law School and former president of the American Bar Association, and Leon Jaworski of Houston, former president of the Texas State Bar Association, has been fully informed at all times as to the progress of the investigation, and has advanced such suggestions as he and his special assistants considered helpful to the accomplishment of the Commission’s assignment. Attorney General Carr has promptly supplied the Commission with pertinent information possessed by Texas officials. Dallas officials, particularly those from the police department, have fully complied with all requests made by the Commission.

THE INVESTIGATION

During December and early January the Commission received an increasing volume of reports from Federal and State investigative agencies. Of principal importance was the five-volume report of the Federal Bureau of Investigation, submitted on December 9, 1963, which summarized the results of the investigation conducted by the Bureau immediately after the assassination. After reviewing this report, the Commission requested the Federal Bureau of Investigation to furnish the underlying investigative materials relied upon in the summary report. The first investigative reports submitted in response to this request were delivered to the Commission on December 20, 1963. On December 18, the Secret Service submitted a detailed report on security precautions taken before President Kennedy’s trip to Texas and a summary of the events of November 22, as witnessed by Secret Service agents. A few days later the Department of State submitted a report relating to Oswald’s defection to the Soviet Union in 1959, and his return to the United States in 1962. On January 7 and 11, 1964, the attorney general of Texas submitted an extensive set of investigative materials, largely Dallas police reports, on the assassination of President Kennedy and the killing of Oswald.

As these investigative reports were received, the staff began analyzing and summarizing them. The members of the legal staff, divided into teams, proceeded to organize the facts revealed by these investigations, determine the issues, sort out the unresolved problems, and recommend additional investigation by the Commission. Simultaneously, to insure that no relevant information would be overlooked, the Commission directed requests to the 10 major departments of the Federal Government, 14 of its independent agencies or commissions, and 4 congressional committees for all information relating to the assassination or the background and activities of Lee Harvey Oswald and Jack Ruby.

After reviewing the accumulating materials, the Commission directed numerous additional requests to Federal and State investigative agencies. The Federal Bureau of Investigation and the Secret Service executed the detailed requests for statements of witnesses and examinations of physical evidence with dispatch and thoroughness. All these reports were reviewed and analyzed by the Commission. Additional investigative requests, where appropriate, were handled by Internal Revenue Service, Department of State, and the military intelligence agencies with comparable skill. Investigative analyses of particular significance and sensitivity in the foreign areas were contributed by the Central Intelligence Agency. On occasion the Commission used independent experts from State and city governments to supplement or verify information. During the investigation the Commission on several occasions visited the scene of the assassination and other places in the Dallas area pertinent to the inquiry.

The scope and detail of the investigative effort by the Federal and State agencies are suggested in part by statistics from the Federal Bureau of Investigation and the Secret Service. Immediately after the assassination more than 80 additional FBI personnel were transferred to the Dallas office on a temporary basis to assist in the investigation. Beginning November 22, 1963, the Federal Bureau of Investigation conducted approximately 25,000 interviews and reinterviews of persons having information of possible relevance to the investigation and by September 11, 1964, submitted over 2,300 reports totaling approximately 25,400 pages to the Commission. During the same period the Secret Service conducted approximately 1,550 interviews and submitted 800 reports totaling some 4,600 pages.

Because of the diligence, cooperation, and facilities of Federal investigative agencies, it was unnecessary for the Commission to employ investigators other than the members of the Commission’s legal staff. The Commission recognized, however, that special measures were required whenever the facts or rumors called for an appraisal of the acts of the agencies themselves. The staff reviewed in detail the actions of several Federal agencies, particularly the Federal Bureau of Investigation, the Secret Service, the Central Intelligence Agency, and the Department of State. Initially the Commission requested the agencies to furnish all their reports relating to the assassination and their relationships with Oswald or Ruby. On the basis of these reports, the Commission submitted specific questions to the agency involved. Members of the staff followed up the answers by reviewing the relevant files of each agency for additional information. In some instances, members of the Commission also reviewed the files in person. Finally, the responsible officials of these agencies were called to testify under oath. Dean Rusk, Secretary of State; C. Douglas Dillon, Secretary of the Treasury; John A. McCone, Director of the Central Intelligence Agency; J. Edgar Hoover, Director of the Federal Bureau of Investigation; and James J. Rowley, Chief of the Secret Service, appeared as witnesses and testified fully regarding their agencies’ participation in the matters under scrutiny by the Commission.

COMMISSION HEARINGS

In addition to the information resulting from these investigations, the Commission has relied primarily on the facts disclosed by the sworn testimony of the principal witnesses to the assassination and related events. Beginning on February 3, 1964, the Commission and its staff has taken the testimony of 552 witnesses. Of this number, 94 appeared before members of the Commission; 395 were questioned by members of the Commission’s legal staff; 61 supplied sworn affidavits; and 2 gave statements.[F-4] Under Commission procedures, all witnesses were advised that they had the right to the presence and the advice of their lawyer during the interrogation, with the corollary rights to raise objections to any questions asked, to make any clarifying statement on the record after the interrogation, and to purchase a copy of their testimony.[F-5]

Commission hearings were closed to the public unless the witness appearing before the Commission requested an open hearing. Under these procedures, testimony of one witness was taken in a public hearing on two occasions. No other witness requested a public hearing. The Commission concluded that the premature publication by it of testimony regarding the assassination or the subsequent killing of Oswald might interfere with Ruby’s rights to a fair and impartial trial on the charges filed against him by the State of Texas. The Commission also recognized that testimony would be presented before it which would be inadmissible in judicial proceedings and might prejudice innocent parties if made public out of context. In addition to the witnesses who appeared before the Commission, numerous others provided sworn depositions, affidavits, and statements upon which the Commission has relied. Since this testimony, as well as that taken before the Commission, could not always be taken in logical sequence, the Commission concluded that partial publication of testimony as the investigation progressed was impractical and could be misleading.
