Over the Line: Homeland (In)Security and the United States' Expanding Borderlands

Abstract

Since September 11, 2001 the U.S. Border Patrol has grown from 9,821 to 20,273 agents, more than doubling in size and in the process becoming the largest federal law enforcement agency in the United States. This dissertation queries the everyday geographies of the agency's practices; the ways that these geographies intersect with and affect circuits and practices of human migration; how the Border Patrol conceptualizes "threat" and maps this onto people and territory they may then police; the environmental conditions that limit or constrain the everyday reach and efficacy of Border Patrol operations in the remote Arizona desert; the discourses, anxieties and everyday conditions of encounter in rural border regions that drive some residents to call for an even greater increase in border policing; and finally, social movements in the City of Tucson, AZ that have sought to combat, resist and undermine immigration policing through the fabric of everyday life. The dissertation draws from two years of fieldwork in southern Arizona and southeast Michigan examining the complex interactions between residents, civil society actors and law enforcement personnel. Research methods included archival research; semi-structured interviews; and ethnographic observation alongside non-governmental organizations, non-status immigrants and at Homeland Security trade events. The research contributes to geographic literatures on security, migration and border policing in the United States, applying posthumanist theory and feminist methodologies to unpack how material conditions of encounter shape state security practice, how this security practice in turn affects people's everyday conditions of social reproduction, and how these everyday conditions of social reproduction may in turn shape or compel social movement practices that contest these outcomes.
