I have written before about the campaigns of vilification, misinformation and undiluted hatred directed at The USA's J. Edgar Hoover - longterm boss of the FBI.
They waited until he was dead, of course. Did he commit the ultimate and most unpardonable sin - falling out with the Kennedys?
The article below is strongly recommended if you want a more balanced view of a man who was far from perfect but did not deserve so much negative propaganda.
