This would be like a 2001 intelligence report on a suspected terrorist neglecting to mention that he had just met with Osama bin Laden. CIA headquarters was keeping its knowledge of the Oswald–Kostikov connection close to its vest. The CIA’s silence regarding Kostikov was maintained just long enough for Oswald to be moved quietly (without being placed on the FBI’s Security Index) into a position overlooking Dealey Plaza on November 22. After the assassination, the CIA used its dormant Mexico City documents to link the accused assassin Oswald with the KGB’s Kostikov.
