39 years after the assassination of President John F. Kennedy, the truth finally comes to light: In 1996, Robert Trumbull Crowley, former Assistant Deputy Director of Clandestine Operations of the CIA, gave documents of his own top secret operations to his friend, historian Gregory Douglas.

After Robert Crowley died in late 2000, Gregory Douglas now begins publishing important sections of the Crowley Papers. This is the first of a series of shocking revelations of the secret plots of top officials of the U.S. government. More information can be read here:

“OPERATION ZIPPER” was the code name for the forced removal of John F. Kennedy, President of the United States of America. This operation was implemented with the help, approval, and/or knowledge of the FBI, the Joint Chiefs of Staff of the U.S. Army, and the Vice President Lyndon B. Johnson, under the aegis of the CIA.

Backed-up with documents reproduced in the book, Douglas proves, which individuals plotted to kill John F. Kennedy, why they thought that this assassination was justified, how it was done, who else was involved, and how the cover-up of this major clandestine operation was mounted.

 As is well known, the rise of Fidel Castro as communist dictator of Cuba led to a series of very dangerous confrontations with the U.S., for instance the failed Bay of Pigs invasion and the subsequent Cuban Missile Crisis, to name only the best known events.

    It is less well-known that both the U.S. Joint Chiefs of Staff and the CIA were plotting to drag the U.S. into open hostilities with Cuba by staging “Cuban aggressions”, and to intentionally cause “collateral damage” outside and inside the U.S., in other words: to kill innocent civilians, including U.S. citizens, and blame it on Castro in order to supply a reason for a military invasion of Castro’s Cuba.

    When U.S. President John F. Kennedy discovered this treasonable program, he intervened and prevented what would certainly have triggered a nuclear world war. In order to prevent another such clandestine intelligence horror, Kennedy felt strongly that it was an urgent necessity to circumvent both the Joint Chiefs of Staff and the CIA who obviously were extremely determined to force a dangerous war on his administration. He and his brother Robert, the Attorney General, decided that any official attempt on their part to establish a rapprochement with the Soviet Union would be doomed to failure by the actions of his own intelligence agencies.

    By dealing with the Soviets behind the back of the CIA, John F. Kennedy unwittingly signed his own death sentence, because many high officials within his administration now considered him to be a traitor.


The Author

The author of Regicide, who writes his historical books under the pen name “Gregory Douglas”, was born in Germany in 1933. He and his family immigrated to the United States in 1934. The author is a nephew of a certain Heinrich Müller who happen to have become Chief of the German Secret State Police “Gestapo” in 1934.

    Müller, an expert in communist counter-espionage, was hired in 1948 by the CIA under the Truman administration in order to fight Stalinist infiltration in the U.S. Within the CIA, Mueller was controlled by CIA agents Robert T. Crowley and Colonel James Critchfield. It was this former Gestapo-Müller who instigated the McCarthy hysteria against Communists and Socialists in the U.S. Robert T. Crowley involvement with Gestapo-Müller was confirmed in 2001 by Joseph Trento in his The Secret History of the CIA, and Müller’s employment by the Truman administrations was also confirmed by Senator Alfonse D’Amoto in an article published in the CIA-internal magazine Periscope in 1997.

    It was not before 1963 that, by pure chance, the author found out about his uncle’s presence in the U.S. Due to them being related and having similar character features, the author quickly became Müller’s best friend. Until Müller died in 1983, they spent many years together discussing the past and poring over stacks of documents Müller had salvaged when he left Europe in 1948.

    The author has published four works on his uncle, Hitler’s Gestapo Chief, Heinrich Müller (The 1948 Interrogation of Gestapo Chief Heinrich Müller, vols. 1-3, Müller Journals: The Washington Years), which were translated into German, Russian, and Japanese. The material for these books partly stems from Heinrich Müller himself, and partly from Robert T. Crowley.

    The author became acquainted with Robert Crowley in 1993 through the offices of John Costello, the British writer. The fact that the author was related to Heinrich Müller, Crowley’s former CIA co-worker, certainly helped opening doors. When the author prepared to published his books on his uncle Heinrich Müller, based on Müller’s private papers and interviews with him, Bob Crowley proved to be most helpful with documents. Mr. Crowley acknowledged the author’s courage and no-nonsense approach in publishing his uncle’s papers, which contradict many myths and paradigms of “politically correct” writings on World War II history and the immediate post-war era. As a result of this cooperation, a close friendship developed between the author and Crowley. The author spoke with Bob Crowley at least twice a week from 1993 through 1996. In that year, Crowley went into hospital for exploratory surgery. This proved to be too great a shock to his system and his short-term memory, which was not good anyway, failed completely.

    Prior to his hospitalization, Crowley sent the author two largish boxes of documents. He did so because if he died on the table, as he feared, he thought that Emily, his charming wife, would not know what to do with his papers. He felt that the author could use some, or all, of these in future writing projects. The caveat was that the author could not use them until Crowley’s death. Bob Crowley died in October of 2000 and the caveat expired. When the author put it about that he had sent him documents, he was visited by an official agency and told that he might get into “serious legal trouble” if he did not promptly give them everything. This threat alone was revealing. The author responded to this threat by putting a list of CIA people (some 4,000), which Crowley had given to him, up on the Internet. He has not been approached since.

    The author occasionally contributed to the Military Advisor magazine and to various historical journals both in the United States and Europe. As an investigative reporter, the author wrote a series of articles on art frauds that resulted in exposure of the notorious Rodin frauds, and was instrumental in uncovering massive thefts from a secure Department of State archive in Berlin in 1995. In 2000, his historical research led him to the discovery of a treasure of gold coins buried beside an Austrian lake by a fleeing Nazi leader, Odilio Globocnik. Presently, the author is working on several other books about recent historical topics, using documents obtained from the late R. T. Crowley, former Assistant Deputy Director of Clandestine Operations for the CIA. The author lives in Illinois.

1. What is the general theory of the book regarding who killed JFK and why he was killed?

    The documents and R.T. Crowley’s accounts prove that J.F. Kennedy was killed through a conspiracy involving major sectors the US administration — CIA, FBI, US Army, Vice President — in order to neutralize Kennedy’s politics of rapprochement to the USSR, which they deemed to be high treason.

3. What have you done to verify that the documents reproduced in the book are genuine?

    The publisher of this book verified that Gregory Douglas was indeed in close contact with Bob Crowley in the 1990s. This fact is known by Crowley’s wife and his son as well as by former FBI agent Thomas Kimmel, grandson of the late Admiral Husband Kimmel (Pearl Harbor). It was also confirmed that a box of Crowley’s documents was shipped by Crowley’s relatives to Douglas, though the content was unknown to them.

    In spring of 2002, famous JFK expert Nigel Turner, who has produced many well-known documentaries about the JFK assassination, contacted both the author and the publisher of this book. After his thorough interviews, he explained to the publisher the following:

  • It is plainly obvious that neither the author nor the publisher of Regicide have any in-depth knowledge neither of the JFK assassination, nor of the era, nor of any persons involved.

  • It is striking, though, that all the facts described in the documents presented in Regicide are in accordance with his 30 years of research on the topic: facts, dates, persons involved, their ranks, whereabouts, responsibilities etc.

  • There are also no formal discrepancies in letterheads, signatures, typewriters used etc.

  • Therefore, if these documents are forgeries, for which there are no indications, they must have been forged by somebody who was extremely well-informed about all aspects of the issue. The primary suspect would, of courses be Crowley himself.

  • However, it would probably make little sense for Crowley to produce a forgery that incriminates himself, his friends and former associates, and his beloved CIA.

  • It seemed to Mr. Turner that the riddle about the JFK assassination was finally solved by one of the assassins finally “speaking out”. One may regret that the documents were not handed over to a well-established historian, but considering Crowley’s somewhat dubious background as the CIA’s liaison man  to the Chicago mob, one would not expect him to act any different than he did.

Prof. Fetzer, a known expert in the field of forensics regarding the JFK assassination, was initially enthusiastic about this book. Later, however, he changed his mind, mainly for reasons (see his current endorsement):

  1. According to Fetzer, his findings about how many shots were fired upon Kennedy do not concur with a statement made in a document published in Regicide, therefore this document must be a forgery.

  2. The ZIPPER document is too good a “smoking gun” to be true. Prof. Fetzer considers it highly unlikely that such a document of all events leading up to the assassination would have been prepared and preserved.

Prof. Fetzer’s skepticism is, however, unfounded:

  1. Neither the authors of the DIA Report nor Prof. Fetzer have definite knowledge of how many shots were fired at JFK. The only people who could testify to this — the two snipers — were processed to crab fodder afterwards. Since the FBI tempered with the evidence, all that the DIA investigators and Prof. Fetzer can do is draw conclusions from accessible evidence. Maybe the DIA investigators of 1978 got it wrong and Prof. Fetzer, in 2003, knows it better, or maybe it is the other way around, or maybe both are wrong and the truth lies elsewhere. A (presumed) factual error in the DIA report does not prove that it is a forgery. It does prove that those guys made a mistake. And vice versa: the possible fact that some errors can be found in forensic papers published under the name of Prof. Fetzer would not prove that these papers are actual forgeries. They just prove that Prof. Fetzer is fallible, too.

  2. With the line of reasoning “this is too good to be true”, every existing document on earth can be dismissed without any further ado, thus this is an invalid argument. However, consider this: any witness with knowledge about the JFK assassination could be considered dangerous to those responsible. If Crowley was indeed one of the main players in the assassination, he was also one of the main witnesses. How could he make sure that he will not be taken care of as well, as were Oswald, Ruby, the snipers, and many others? First, he had to be loyal to his employer; secondly, he had to not even hint at a possibility that he would open his mouth; thirdly, he needed to make sure that those who would consider killing him would fear that his death could lead to the release of some ugly documents. Thus, the ZIPPER document and the other documents in Crowley’s possession could have been a very effective life insurance. This is a method of self-protection that is very common under people involved in this kind of dirty business.

And here comes the author’s take on this question:

    Most “questioned document” specialists who are usually approached to verify the authenticity of documents work for the Justice Department. But if the documents shown in the book are genuine, the whole government was behind the Kennedy assassination and can therefore not be trusted. Hence, I bypassed them. Having been involved in exposing the notorious “Hitler Diary” fraud some years ago, I had learned that certain “document specialists” will either authenticate or deny anything they are paid, or told to do.

All documents received from R.T. Crowley are photocopies. There are no “originals.” Given that, all an “expert” can do is to verify the origins and time frame of the typewriters used, the originality of the one letterhead (Defense Intelligence Agency) and the signature of the person on the cover letter. To this end, I have had several typewriter specialists look at the documents. It is their unanimous opinion that the machines used were of the period. It was also confirmed that Colonel Driscoll was indeed in the position indicated on the cover letter during the time in question and that all of the individuals mentioned in the documents were also in place at the time of the ZIPPER operation. Additionally, the material contained in these documents is of such a detailed and highly confidential nature as to preclude someone forging them.

If the government does not like what I publish, it is for them to prove that the supporting documents are not authentic. This is not my responsibility. Also, I ignore statements such as “I just cannot believe this” or “We talked to the widow of so and so and she said her husband could never have been involved in such business.” Statements like these are completely worthless and to be ignored for what they are: self-serving nonsense.

I have shown a number of the Crowley files to friends of mine who have served in various U.S. and foreign intelligence organs for years, and not one of them questions the authenticity of the material, although all deplore its revelation to a public that will certainly have no problem with belief. In the final analysis, it doesn’t matter what the official establishment thinks — if, in fact, they think at all. The American public does not believe controversial matters until they are officially denied in Washington.

The matters set forth in the book are not circumstantial. For instance, the official log of the plotters is far more than circumstantial but the key document. A lengthy, signed report by the DIA is most explicit in stating that the CIA killed Kennedy and sets forth their very plausible reasons and evidence.

In contrast to the other thousands of authors who wrote books on the assassination of JFK, I am in the fortunate position of having documentation. If there was any other public documentation, it has been long ago destroyed or hidden. After all, that Imperial British couplet, very popular at the turn of the last century, may be recalled:

“Whatever happens,
we have got the Maxim gun,
which they have not.”

4. Why would R.T. Crowley give those documents to you and not to a high profile investigative journalist, like Seymour Hersh?

    During the final years of his life, R.T. Crowley was a very lonely person, abandoned by former friends and colleagues. One of the few person he was able to talk to in these years was Gregory Douglas. He was Crowley’s last and most loyal friend.

By publishing his controversial books on his uncle Gestapo Müller (see the author’s biography), Douglas had furthermore proven to Crowley that this author had the courage to publish historically and politically highly controversial material, writing it according to the documentary evidence instead of bowing, bending and falsifying it on the altar of political correctness.

Finally, Crowley quickly realized that Douglas was highly suspicious of any authority and very sophisticated and experienced in dealing with them, which is a necessary prerequisite if one wants to publish material that the power elite wishes to suppress.

It was therefore only natural for Crowley to give all his documents to this loyal and skilled friend.

5. Why is this book not published by one of America’s major publishing houses?

    Major publishing houses have a great deal to lose — money, reputation, influence, power — and therefore are very susceptible to official pressure. They also are very often “mainstream” and pay attention to what is wanted or expected from the establishment even without pressure. Gregory Douglas therefore chose a small, dedicated publisher who will be loyal to this project, what ever may happen.
