Harry Dean - Wade Rhodes posted this on the JFK Forum (see links) and Frank Agbat was good enough to transcribe it. I have a lot of documents on Harry Dean and will eventually put together a research project on him. Any information on Harry Dean is appreciated.

In an exclusive interview granted to Between the Lines, former undercover operative for the FBI, Harry Dean, has stated that the John Birch Society and the Drive Against Communist Aggression (DACA) had a heavily armed network of citizen soldiers ready to take to the streets in late 1963 and early 1964, if President Johnson and Chief Justice Warren did not quickly find Lee Harvey Oswald (a supposed communist sympathizer) guilty of the murder of President Kennedy. The thread was delivered to Johnson and Warren, within a few days after the assassination, but intelligence sources and by agents of the power structure that eliminated the President. LBJ had the choice - nation-wide internal strife or knuckling under to the thread and thereby giving the minority force a position of recognition. Johnson opted for the second choice.Dean, an undercover operative for the FBI from 1960 to 1965, had been assigned by the FBI to infiltrate the Birch Society. During Dean's tour with the Covina Chapter of the Society he states they planned three major activities against John Kennedy: a planned assassination in Mexico City in 1962 that was called off; the assassination in Dallas, and the threat against a thorough investigation. In each case, according to Harry Dean, Congressman John Rousselot (Rep. San Marino) was involved in the planning. Rousselot was Western Director of the JBS during the first half of the '60's.During the years when Harry Dean had been acting as an active member of the Covina Birch Society, the main meeting place for all the anti-Kennedy activities was at the a residence on San Pierre Street in El Monte. The Birchers were connected with anti-Castro Cubans, often mentioned as assassination suspects, through the DACA. The DACA was an anti-Communist organization directed by members of the JBS, which had attracted certain Cubans who were in the Los Angeles area during 1962-1963, trying to enlist support in another invasions of Castro controlled Cuba. The DACA operated in Mexico as well as the U.S.. According to Dean, World War II hero Guy (Gabby) Gabaldon was the Mexican Director, while Ray Fleishman of Whittier was the U.S. Director. Another active member of DACA and the Covina JBS, who had a close relationship with Gabaldon, was Dave Robbins, who at the time ('62-63) was a high ranking employee of the Fluor Corporation. (J. Robert Fluor and John Rousselot had been known to be close political allies). In a number of different circumstances, Dean was able to determine that Gabaldon, Robbins, Flieshman, and Rousselot had been involved in planning the aborted assassination attempt of JFK in Mexico City, June 1962.Harry Dean had many occasions to observe and relate with much publicized Cuban-American Loran Eugene Hall - aka Lorenzon Pacillo - aka Skip Hall and Laurence Howard - aka Alonzo Escuirdo. Hall and Howard had a close association with former General Edwin Walker, of Texas, whenever Walker visited the Covina JBS. Dean recalls specific meetings where Walker, Rousselot, Hall, Howard, Gabaldon, and himself (Dean) laid the plans to frame LHO, who they thought was a communist, as the assassin. Per Dean, Hall and Howard left the San Pierre Street house in October 1963, with arms and medicines, and the plans to implicate Oswald. The subject of eliminating President Kennedy was never discussed as a subject of the Society's meeting, but Harry Dean claims the plans for the assassination were conceived in small-group meetings. At one time or another, Harry Dean was witness to the plans of the assassination of JFK by different combinations of John Rousselot, Loren Hall, Laurence Howard, Guy Gabaldon, Edwin Walker, Dave Robbins, Ray Flieshman, and not previously mentioned Covina JBS member Ed Peters.
