This morning the Miami Herald's Nora Gamez Torres reported a story passed along almost 40 years ago by Ricardo Morales, a former CIA worker and anti-Castro militant and FBI informant. One of Morales' sons claimed on Spanish-language radio that his father, a sniper instructor in the early 1960s in secret camps where Cuban exiles and others trained to invade Cuba, "realized in the hours after President John F. Kennedy was assassinated in Dallas in 1963 that the accused killer, Lee Harvey Oswald, had been one of his sniper trainees."
