"Borderland Circuitry provides a groundbreaking description and analysis of US immigration surveillance databases and a sobering assessment of the costs of our intrusive, racially discriminatory enforcement system. Using research methods that force governmental transparency, Ana Muñiz exposes the insufficiency of technocratic reforms and convincingly calls for an abolitionist stance toward borders."--Jennifer Marie Chacón, coauthor of Immigration Law and Social Justice "Engaging and well-written. Muñiz offers novel insights into the use of databases and technology to facilitate immigration enforcement and surveillance by federal immigration authorities."--Bryce Clayton Newell, Police Visibility: Privacy, Surveillance, and the False Promise of Body-Worn Cameras "A powerful, important book. Weaving together careful research and analysis, eloquent personal reflections, and incisive critique, Muñiz examines the hidden ways in which a sprawling network of digital technologies has fundamentally reshaped gang enforcement and immigration control practices in the United States. The book's urgent call to reassess these developments in light of their devastating human costs deserves wide attention."--Anil Kalhan, Professor of Law, Drexel University
