Police culture has been widely criticized as a source of resistance to change and reform, and is often misunderstood. This book seeks to capture the heart of police culture-including its tragedies and celebrations-and to understand its powerful themes of morality, solidarity, and common sense, by systematically integrating a broad literature on police culture into middle-range theory, and developing original perspectives about many aspects of police work. The first section addresses the definition of culture and the understanding of police culture, while section two moves on to themes of police culture.
