Kennedy first released this book in 1954, the 1990 edition includes some practical ideas to fight Klan and other neo-fascist organizations in an afterword.
This book is a very easy read, conversational in tone, and compelling in content. Mr. Kennedy outlines his infiltration into the headquarters chapter of the KKK in Atlanta and the Columbia Brownshirt organization there, and his undercover hob-knobbing with violent racists and hatemongers, and the colorful illiterates and semi-literates that made up the membership of the Klan and their fellow travellers. He put his life in danger many times confronting the evil, brutal and stupid nature of southern racists.
Another compelling part of the story is the complicity of the police, FBI, the Democratic machine of the Talmadge family, (who rode the upsurge in Klan violence to national political prominence), and the Republican businessmen of the south who paid Klansmen to help bust union drives by busting heads and nightriding.
He also spends alot of time detailing Klan rituals and meetings, and the seemingly neverending lists of Kleagles, Kludds, etc. that made up the hoodoo hierarchy of the Klan organization. It seems like never had so much empty ritual been used in attempt to 'sanctify' such mindless violence.
A good book that gives a good cross-section of what Klan terror and rightist violence was all about in the 1940s and 1950s.
