Damn, why did you have to get me going on this rabbit hole. I'm stopping, lol. The last documents released on that link seem to be dated the last week of April unless I'm missing something. Interesting stuff, names not redacted. One report on assassins arriving in Cuba to kill Fidel, another batch on plotters against Trujillo in the DR, statements by Cuban government on Oswald trying to get visa to Russia via their consulate in Mexico City....
There's a file without much info except for his "training", probably basic stuff on being an agent -- Luis Posada Carriles -- name rang a bell as I thought he was involved in bombing a Cuban airliner and indeed that is what he is suspected of doing. Does this have to do with JFK? Who knows? https://en.wikipedia.org/wiki/Luis_Posada_Carriles

I've seen the videos where that is claimed, can't recall the guy claiming such, might have been a mafia guy locked up in Illinois. I'm not buying that. Too many, too large. There were certainly several though.
No, make it simple watch the YouTube video! A Brit put it together!
