"Station WH/Miami is in daily contact with USSS (US Secret Service) in Miami, using JMFALCON as a meeting site when necessary. The location of Station WH/MIAMI (JMCOBRA) has not been revealed to the USSS. (JMCOBRA is located some distance from JMFALCON). Additionally, the Miami Security Field Office maintains normal relations with the local USSS Miami unit."
10/4/68 cable from John K. Greaney of the OGC: "We have been advised by Department of Justice that the US Attorney in Miami will present evidence to the grand jury during the week of 7 October to seek an indictment against Cubans involved in firing a projectile against Polish ship in Miami harbor. Possible defendants are as follows: Orlando Bosch, Barbero Balan Garcia, Jose Diaz Morejon, Aimee Miranda, Andres Gonzalez, Jorge Gutierrez and Paulino Gutierrez. We do not feel that any JMCOBRA action is required but thought you should be prepared for publicity when indictment handed down. This info should be discussed with other government agencies only with the greatest discretion."
