Oswald's alleged threat to kill JFK occurred at the Cuban embassy, not the consulate.
Thanks Thomas, that is very interesting. Here is a quote from Latell’s book that says it was at the consulate. There are also three other items that corroborate the belief of advanced knowledge of Oswald:
Four other sources have confirmed that Fidel and the DGI had advance knowledge of Oswald. Vladimir Rodriguez Lahera, the first important defector from Cuban intelligence—fully trusted by the CIA and used in sensitive operations—told his handlers in May 1964 that Castro had lied. The defector was at DGI headquarters in Havana when news of Kennedy’s death was broadcast. It was there that he heard other officers discussing what they already knew about Oswald.9 Alfredo Mirabal, an intelligence officer under consular cover at Havana’s Mexico City embassy, inadvertently revealed in 1978 that in September 1963 he had informed headquarters about Oswald. Jack Childs, a trusted FBI agent in its highly sensitive Operation SOLO, also provided reliable information proving that Castro knew about Oswald before November 1963. Childs’s undercover work included a meeting with Castro in Havana in May 1964 that is described in chapter seven. Remarkably, Castro revealed to Childs that he had been aware that, while at the Cuban consulate in Mexico City, Oswald had threatened to murder Kennedy. And finally, Florentino Aspillaga, the highest-level, most-decorated officer ever to defect from the DGI, is convinced that Fidel had advance knowledge of the assassination in Dallas. Aspillaga’s story is told throughout the following chapters.
I don't think that's right, that the
alleged threat was made at the Embassy. Not that it matters much but all of this - the encounters with Oswald et cetera - was at the Consulate building. The Consulate building and the Embassy were two different buildings although I think the Consulate was connected to the Embassy (it's not clear).
Duran said she worked at the Consulate, which is where Oswald went for the transit visa, and not the Embassy. And Eusebio Azcue, who threw Oswald out, was the Cuban Consul not the Cuban Ambassador.
From Silvia Tirado's (nee Duran) testimony:
CORNWELL - At one time you worked for the Cuban Consulate.
TIRADO - Yes.
CORNWELL - Did you in any other way know any of the other employees at the Consulate?
TIRADO - Yes, well I knew Azcue, Eusebio Azcue who was a consul, and uh, Maria Carman Olivari -- she's dead.
And this indicating that people worked at the Embassy or the Consulate (two separate buildings):
CORNWELL - Now, did you know a Teresa Proenza? Was she employed at the Consulate or the Embassy.
TIRADO - The Embassy. She was the Cultural Attache.
CORNWELL - She would have worked in the area marked number four? Is that correct?
TIRADO - Well, yes. But this was, this construction was uh, afterwards. This was the Embassy and the Consulate and building was under construction, constructed. A building.
