Was J. Edgar Hoover a hero or was he a tyrant?
I have been reading up on him in Richard Hack's book and being halfway through, I am thinking he was not as evil as people might think but he definitely believed so strongly that he was right as to not hesitate to be excessive.
His story really could not be squeezed into a two hour movie though.
