Book excerpt: Pulitzer Prize winning author Leon Litwack calls Brian Willingham's Soul of a Black Cop A scream from the bottom... a compelling and often unnerving documentary portrait of an urban war zone... the day to day experiences of America's interior exiles. The author is a black city cop in the Flint, Michigan, of Michael Moore fame. His beat is the ghetto, where a decaying city has imprisoned its downtrodden. There's no where else to go, and Willingham illustrates this through story after heartwrenching story and his profound comprehension of the human condition. It is a story of eight months in hell. Some say racism doesn't exist; others blame the suffering. A must-read book for all those in any type of social work, indeed a book for all America
