03/10/72: Dispatch from Chief, Western Hemisphere Division to COS, Mexico City: Subject: PBRUMEN/KDAFGHAN - Comments on Proposal to Terminate KDAFGHAN-1 and KDAFGHAN-2 and Recruit New OP Site Team: Page 2: ..."3. While we are more than a little ambivalent concerning the over-all value of this activity as presently constituted, given the priority need for coverage of the AMSTAFF (probably DGI - Direccion General de Inteligencia, aka the General Directorate of Intelligence) personnel stationed at the PBRUMEN (Cuban) Embassy and the relative dearth of PBRUMEN target access agents, we believe that this activity should be continued. We share the Station's concern about our inability to identify the photographs of non-PBRUMEN personnel who visit the Embassy or Consulate, but appreciate the difficult technical problems involved. On a more positive note, the recent group of photographs of PBRUMEN Embassy staffers forwarded to Headquarters for review by AMBEDEW-1 (probably Orlando Castro Hidalgo) and AMWHEN-1 (the latter has not yet been completed) were of high quality. As a result of the high quality of these photographs, AMBEDEW-1 was able to identify still another AMSTAFFer assigned to the Embassy...Meanwhile, the high rate of identification of PBRUMEN visitors to the Embassy currently being achieved by the Station testifies to your determined efforts to obtain the maximum 'take' from this operation...Grover E.

09/19/72: Dispatch from COS, Mexico City to Chief, Western Hemisphere Division: "1. Transmitted herewith are two memoranda concerning the request by a U.S. lawyer to examine some photographs taken in September and October 1963 of an unidentified American entering the Cuban Embassy in Mexico City. The 18 September 1972 memorandum is from local LNERGO (FBI) and provides background - related to an interest in the Lee Harvey Oswald case - of the lawyer's request. Our reply, dated 18 September 1972, is self-explanatory. 2. It appears likely that the lawyer concerned will pursue his interest in the photos, and therefore we want you to be aware of his request.
