Means II

The mob clearly had reason to hate the Kennedys, both because of their Cuban policies and their war on Organized Crime.  It is interesting to note that after John Kennedy’s death, prosecutions of Organized Crime figures declined by 83%, as Robert Sam Anson tells us.  He writes, “Organized Crime had considerable cause for relief; for with Kennedy’s murder…the statistics added up to a quiet, largely unnoticed surrender in the war Robert Kennedy had declared.  It had cost only one casualty: The life of his brother.”

But—and this is a big “but,” no-one in Organized Crime had the means to forge and plant the medical evidence in this case, not to speak of much other incriminating planted and forged evidence against Oswald.  Nor could the Mob engineer the disappearance of evidence from the National Archives.  The Mob could not have covered up the crime.  Only government agencies had people capable of planning and covering up such a murder.
