Policing the Borders Within offers an in-depth, comprehensive exploration of the everyday working of inland border controls in Britain informed by extensive empirical material explored through the lens of wide-ranging interdisciplinary debates. In particular, this book examines afresh the relationship between policing, borders, and social order through the lens of migration policing. By charting this new landscape of everyday contemporary policing, the book’s main goal is to advance understanding of novel forms of law enforcement in a global age. These new forms of collaboration direct attention to the way in which front-line enforcement agents through their everyday work recreate the border, and not just enforce it. As the book argues, the emphasis on borders and migration controls and the growing importance of it within inland everyday policing is a symptom of the new demands and challenges facing the state in exercising authority in a fast-moving, interconnected world, and its attempt to offer a semblance of order. Such challenges result in practice in the random, capricious, informal, and arbitrary operation of power, which relies on non-rational, magic-like elements to solve policing problems. Through an ethnography of the worlds of police and immigration officers, the book dissects the ethical, political, legal, and social dilemmas, tensions, and contradictions posed by the task of maintaining order in a deeply unequal globalized world. The new impetus to police migration is an insightful entry point to understanding law enforcement in a global age.
