The police response to protests erupting on America's streets in recent years has made the militarization of policing painfully transparent. Yet, properly demilitarizing the police requires a deeper understanding of its historical development, causes, and social logics. Policing Empires offers a postcolonial historical sociology of police militarization in Britain and the United States to aid that effort. Julian Go tracks when, why, and how British and US police departments have adopted military tactics, tools, and technologies for domestic use. Go reveals that police militarization has occurred since the very founding of modern policing in the nineteenth century into the present, and that it is an effect of the "imperial boomerang." Policing Empires thereby unlocks the dirty secret of police militarization: Police have brought imperial practices home to militarize themselves in response to perceived racialized threats from minority and immigrant populations.

"Policing Empires painstakingly reveals the colonial roots of modern policing across the globe. Dismissing simple narratives of police militarization or individualized racism, Go shows how racialized fear of crime and the mobilization of counterinsurgency practices have been the organizing logics of the institution of policing." - Alex S. Vitale, author of The End of Policing

"Policing Empires is an important contribution to the rapidly growing field of police history." - Jonathon Booth, Criminal Law & Criminal Justice Books

"Go provides invaluable depth and specificity to a field that is most commonly surveyed from the vantage-point of grand strategy and macroeconomics. Reading this book as militarized American police forces are mobilized to crack down on students protesting the mass slaughter of Palestinians on university campuses further heightens its clear and immediate relevance." - Stuart Rollo, International Affairs
