Schweiker was more blunt, saying that the Warren Commission had "collapsed like a house of cards," and that the Kennedy assassination investigation was "snuffed out before it began" by "senior intelligence officials who directed the coverup." The Schweiker-Hart Report focused on evidence and allegations that Castro was behind the JFK assassination, but also uncovered indications that these were part of a frame-up.

So, who killed JFK?...One clue is the pre-assassination events which served, after the assassination, to focus blame on Fidel Castro - particularly the impersonation of Oswald in Mexico City. Far from showing Castro's guilt, this is a red flag pointing in the direction of those who despised JFK for his perceived inaction on Cuba. Some of the earliest researchers focused their suspicions on the coalition of Cuban exiles, mob members, and CIA officers who conspired to eliminate Fidel Castro. Many of the circumstantial leads, and indeed confessions of guilt, still lie in that direction.
CIA files declassified in the 1990s provide tantalizing clues in regards to the compartmentalization of knowledge about Oswald and actions which would later be used to spin the "Communist assassin" angle. Oswald's records were tightly held in James Angleton's CounterIntelligence division, shielded from other parts of the CIA - which were fed false information. Legendary CIA propaganda artist David Phillips recurs in this story in unexplained ways, as do others involved in the CIA-Mafia plots, such as Johnny Roselli.
The old adage "someone would have talked" may not apply to professional killers and sophisticated organizations. The Church Committee, with full Congressional backing and subpoena power, was still unable to get to the bottom of some basic questions about the plots to kill Fidel Castro, including the simple question of whether Presidents Eisenhower or Kennedy actually authorized them. The Committee ran into a system of "plausible deniability," cut-outs, and need-to-know information handling that made that task simply impossible. If it weren't for this unusual Committee, CIA plots to murder Castro might still be regarded as a "conspiracy theory."
