39 years after the assassination of President John F. Kennedy, the truth finally comes to light: In 1996, Robert Trumbull Crowley, former head of Clandestine Operations of the CIA, gave documents of his own top secret operations to his friend, historian Gregory Douglas. After Robert Crowley died, Douglas begins publishing shocking revelations of the secret plots of top officials of the U.S. government. ?OPERATION ZIPPER? was the code name for the forced removal of 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.Douglas, Gregory is the author of 'Regicide The Official Assassination of John F.
