In this groundbreaking exposé, Stuart Schrader shows how the United States projected imperial power overseas through police training and technical assistance—and how this effort reverberated to shape the policing of city streets at home. Examining diverse records, from recently declassified national security and intelligence materials to police textbooks and professional magazines, Schrader reveals how U.S. police leaders envisioned the beat to be as wide as the globe and worked to put everyday policing at the core of the Cold War project of counterinsurgency. A “smoking gun” book, Badges without Borders offers a new account of the War on Crime, “law and order” politics, and global counterinsurgency, revealing the connections between foreign and domestic racial control.
