continuing with WEDGE. FROM PEARL HARBOR TO 9/11 HOW THE SECRET WAR BETWEEN THE FBI AND CIA HAS ENDANGERED NATIONAL SECURITY by MARK RIEBLING.

first chapter is Angleton's appearance as CIA,and ends with the Gary Powers fiasco.I found the authors's last little tidbit on the
Powers event and aftermath very interesting because I was unaware of that information on the person named...

second chapter it turns out was very much connected to the last comment in the previous chapter...

....But the October 1963 report was not passed to CIA. Nor did the Bureau tell the Agency about allegations that Santos Trafficante, the key figure in CIA’s preCubela assassination attempts, was also really working for Castro—and that the president’s life might be in danger. This information came to the FBI from Jose Aleman, an anti-Castro exile in Miami. Aleman had been a co-conspirator with Cubela during the revolution, but afterward became disillusioned with Castro’s overt Marxism and emigrated to the U.S. By September 1962, one of Aleman’s distant cousins, who had allegedly helped spring Trafficante from a Cuban jail, had introduced Aleman to the mobster at a Miami Beach hotel. Disturbed by what had transpired at that meeting, Aleman immediately began informing on Trafficante to George Davis and Paul Scranton of the FBI’s Miami Field Office. Trafficante had offered to get him a loan from Jimmy Hoffa’s International Brotherhood of Teamsters, and while they were on that subject, Trafficante had mentioned, in passing, that because of the Kennedy administration’s harassment of certain individuals, JFK was finished. According to Aleman, Trafficante had said simply, “He is going to be hit.”

Such words would seem ominous enough in hindsight, but at the time Trafficante’s hints were apparently judged mere gangland braggadocio. Aleman got little reaction from the FBI when, starting in late 1962 and continuing through the summer of 1963, three Cubans he had known in Havana appeared in Miami and then left for Texas. Aleman suspected them of being Cuban agents and, he later said, told this to the Bureau. “I advised the FBI in long conversations that I thought something was going to happen, ” Aleman said. “I was telling them to be careful.” Thirty years later, with Bureau records of his debriefings remaining classified, Aleman’s accusations would resist positive confirmation. But FBI agent Davis, when advised of Aleman’s allegations, would affirm: “He’s a reliable individual.”

A possible threat to the president’s life was only part of Aleman’s dark message. He was also convinced that Trafficante was tied in to Cubela, and that both Trafficante and Cubela were agents of Fidel Castro. He did not then know that Trafficante was the point man for CIA’s attempts on Castro’s life, or that Cubela was CIA’s “mole” in Castro’s junta. He only knew that Cubela and Trafficante were “linked” and that, as he said, “something was wrong in some way.” Cubela was a closet communist, and the whole Trafficante story was suspicious. Both before and after the revolution, Trafficante had run a corrupt bolita (numbers racket) that was used to pay off Castro’s secret agents. (Aleman did not know it, but such suspicions were paralleled in a Federal Bureau of Narcotics memo dated July 21, 1961, reporting rumors that Castro had kept Trafficante confined after the revolution merely “to make it appear that he had a personal dislike for Castro, when in fact Trafficante is an agent of Castro, ” his “outlet for illegal contraband in the country.” The Narcotics Bureau memo also confirmed Aleman on the bolita scheme, stating outright, “Fidel Castro has operatives in Miami making heavy bets with Santos Trafficante Jr.’s organization.”)
