The short answer is I don’t know.
The long answer is that we are talking about one of the most pregnant moments in the Warren Commission’s efforts to obtain information from the CIA. It happened in March 1964.
Former HSCA investigator Dan Hardway has written about this remarkable incident. It is often cited in the JFK literature. I want to revisit it in closer detail.
I’m going to tell the story in my forthcoming biography of Angleton, and I want to get the details right. Maybe you can help.
In February 1964, the Warren Commission general counsel Lee Rankin asked the agency to provide copies of three cables from the Mexico City station chief Win Scott to CIA headquarters. The commission staff knew about the cables because copies had been shared with the Secret Service on the night of November 22, 1963.
(This February 20, 1964 CIA memo tells the back story.)
When this reasonable request went to Angleton, chief of the Counterintelligence Staff, he balked. Angleton told his deputy Ray Rocca that he “would prefer to wait out the Commission” rather than turn over the cables.
Rocca laid out “the problem” for deputy director Dick Helm in this March 5, 1964 memo.
Unless you feel otherwise, Jim would prefer to wait out the Commission on the matter covered by paragraph 2.
These cables were identified by the numbers 66846, 66891 and 66896.
If someone can pull these cables from Mary Ferrell, I will post them and we can discuss Angleton’s possible motives for not sharing this evidence with assassination investigators. This is a telling moment in the JFK story worth understanding.
