Morley simply won't - or can't - believe that these anti-Castro Cubans could act on their own, that they would respond to Oswald independently, without guidance. He sees the guiding hand of the CIA all around this matter. This is the JFK conspiracy Left; now with MAGA helping them. But he also admits, in a sotto voce sort of voice, that the DRE were notoriously independent, hard to control. The CIA/DRE relationship seemed to be particularly difficult. But he doesn't see any independence here even though Bringuier himself says he acted on his own.
Questions: Wouldn't the other DRE members who were supposedly directed by GJ inform Bringuier of this? Explain why they were doing what they were? Tell him about GJ? And if they informed GJ after the assassination about what they did with Oswald wouldn't that mean he didn't direct them before? Why the need to tell him? He already knows it since he ordered it.
It seems to me that the more interesting person that could possibly point to some external direction would be Stuckey. He said after interviewing Oswald that he transcribed it and gave it and the tape to the FBI. That's an odd reaction for a journalist. He also said an unnamed source told him about Oswald's defection. I would guess that source was Butler. Instead of focusing on the DRE I think Stuckey/Butler and the FBI would be more likely if there was direction.
Interesting (to me) fact about the DRE: I just read recently that it was the DRE members who were still in Cuba that were among the first there to inform the CIA about the Soviet missiles. The CIA agent Roger Crozier, who preceded Joannides as control agent, reportedly was frustrated that his reports about the missiles would go to Washington and disappear. The CIA simply didn't trust the DRE reports. So it seems that the CIA/DRE mistrust has a history.
