In the days after the murders in Dallas, the U.S. Was flooded with dubious stories, most of them swiftly discredited, linking Oswald to either a Cuban or Soviet conspiracy. Those which most preoccupied the FBI and CIA all came out of Mexico. These stories exhibited certain common characteristics.
- They all came from either directly from an intelligence source, or from someone in the hands of an intelligence agency. Nearly always the agency involved was the Mexican DFS or secret police. The DFS, along with the Nicaraguan intelligence service, which was also a source, were under CIA tutelage.
- The Stories changed over time, to support either a pro-conspiratorial hypothesis (“Phase One”) or a rebuttal of this (“Phase Two”).
- The Warren Commission was led to believe that the “Phase One” stories were without basis. In fact a number of unresolved anomalies suggest that behind them was some deeper truth, still not revealed.
- As just noted, the two main sources, Silvia Duran and Gilberto Alvarado, gave varying stories while detained by the DFS. Of the two, Duran was actually tortured, and Alvarado reportedly threatened with torture... In retrospect, these stories should not have been taken seriously. In fact the CIA was able to rely on them, not as a source of truth, but as a source of coercive influence over the rest of the government. It will help us to understand what was going on if we refer to the stories, not as 'information' or even as 'allegations,' but as MANAGED STORIES. To say this leaves open the question of who were the ultimate managers – the DFS, U.S. Officers in Mexico, or higher authorities in Washington.
The full history is complex and confused, with many unanswered questions. But nearly all of these managed stories, along with others outside Mexico.....resolve into this simple pattern of a Phase One/Phase Two evolution.
I do wish to argue that these managed stories, fleeting and insubstantial though they are, were of central importance in determining the outcome of the Kennedy assassination investigation. In succeeding years, furthermore, the discredited 'Phase-One' stories have been revived to manipulate public opinion, even after the CIA and FBI had agreed on a 'Phase-Two' interpretation of Oswald's movements in Mexico City. In 2013, for example, the discredited Garro story of the twist party was revived in a mainstream book by Philip Shenon.
To this day both ':Phase-One' and 'Phase-Two' versions are trotted out from time to time. These control public perceptions of the Kennedy assassination seize the debate from genuine critics who have less access to the media.
