Assassination Records Review Board JFK Document Exhibits Commentary by T. Jeremy Gunn, ARRB Executive Director Exhibit A     Cable to the Mexico City Station from     CIA Headquarters, November 27, 1963. This document was released in full after a Board vote in 1995. The second line of typed text includes the crypts (or cryptonyms) "RYBAT" and "GPFLOOR." These crypts appear in the "slug line" and they are routing and sensitivity indicators. "GPFLOOR" is the crypt that refers to Lee Harvey Oswald. This same crypt appears in the first line of the second paragraph of text. CIA originally advised that GPFLOOR could not be released in the slug line although it could be released in the text of the cable. Exhibit B     Letter to the Legal Attache in Paris     from the Director of the FBI, October 12,1960.     Subject: Lee Harvey Oswald - Internal Security. This document was one of several records exempted by the FBI because it contained foreign government information. The stamps on the page suggest that the document was reviewed in 1977 and stamped exempt from declassification. This document was re-reviewed in 1992 and severely redacted. The Review Board, with the assistance of the Department of State, approached the Swiss Government and requested that it consent to the release of the information. In December 1995, the document was released in full after a Board vote and with the concurrence of the Swiss Government. Exhibit C     Memorandum to the Secretary of Defense     from the Joint Chiefs of Staff, January 31, 1964.     Subject: A Contingency Plan for a Coup in Cuba. The Review Board located several Top Secret documents related to military contingency planning for a coup in Cuba. This exhibit contains one page from a 58-page document formerly classified Top Secret--Sensitive. The document was excluded from automatic declassification and was unavailable to the public in any form. It was systematically reviewed in October 1989 and the classification was continued. This document and many similar documents were opened in full at a declassification session in July 1997 after review by representatives of the Joint Chiefs of Staff, the CIA, the National Security Council, and the Office of the Secretary of Defense. Exhibit D     (a) Vietnam January-August 1963,     Foreign Relations of the United States, Vol. 3. pp. 265-270.     (b) Memorandum for the Record of the     Eighth Secretary of Defense Conference on     Vietnam, May 6, 1963, Honolulu, Hawaii. In May 1963, Secretary of Defense Robert McNamara met with military advisers in the eighth of a series of conferences on Vietnam in Honolulu, Hawaii. Part (a) of this exhibit includes all of the material that had been publicly released on the conference prior to Review Board action (a 6-page summary published in Foreign Relations of the United States) and part (b) includes the title pages of the full 213-page Record [of the] Eighth Secretary of Defense Conference from the Joint Chiefs of Staff Official File that has now been opened in full. Prior to Review Board action, the memorandum had been excluded from automatic regrading and declassification and could presumably have remained classified forever. A stamp on page 1 discloses that the document was systematically reviewed by JCS in May 1989, and the classification of Top Secret was continued. The document was opened in full at an ARRB declassification session in July 1997. Exhibit E     Monthly Operational Report 1-30 September     from the Chief of Station, Mexico City     to Chief KURIOT, October 18, 1963. The CIA typically is reluctant to release information regarding technical surveillance. This document is a CIA monthly operational report for Mexico City for September 1963, a period that includes Lee Harvey Oswald's arrival in the Mexican capital. The attached form discloses that this document was reviewed in 1993 and postponed in its entirety. It was opened in full in 1995 after a Board vote. Exhibit F     NSA SIGINT product report, November 26, 1963. The Review Board has had some success in releasing NSA records. This document discloses NSA's intercepts of communications related to Cuban military alerts after the assassination of President John F. Kennedy. It was originally unavailable to the public in any form and was exempt from automatic declassification. This document was released with sanitizations by Board vote. Exhibit G     Memorandum to McGeorge Bundy     from Gordon Chase, June 15, 1964.     Subject: Assassination of Castro. This document from the files of the National Security Council was originally classified "Secret" and was exempted from declassification in 1976. The NSC agreed to release it in full after discussions with the Review Board in 1998. Testimony of ARRB Director T.
