I'm a librarian who loves anime, manga, and reading a wide variety of genres.
The timeline's a little hard to follow. On page 88, Stallworth is "anxiously" calling David Duke about the status of his KKK membership card. On page 84, Stallworth writes about becoming a strange sort of celebrity among criminal justice officials, who'd see him at the cop bar, offer to buy him a drink, and ask to see his KKK membership card. (This entire section seemed a bit weird to me. Wouldn't it have been seen as a potential problem that the investigation was such a badly kept secret?)
