This book examines the relationships forged between police officers and the diverse urban and rural communities in which they have lived and worked in Scotland across the twentieth century, demonstrating patterns that were diverse and variegated. It considers both the formal rhetoric (and sets of structures) that defined and prescribed the policing ideal as well as the experience of policing from a range of grassroots' perspectives. Drawing on a wealth of archival materials, oral history interviews, and memoirs, as well as previously unused primary sources, the author identifies and explains the factors that led to not only co-operation, consensus and the building of trust, but also points of tension and conflict across a century of social, political and technological change.
