ABSTRACT Following the tragic events of 9-11, top Federal policy makers moved to establish the Department of Homeland Security (DHS). This massive realignment of federal public safety agencies also loosely centralized all U.S. civilian security organizations under a single umbrella. Designed to respond rapidly to critical security threats, the DHS was vested with superseding authority and broad powers of enforcement. Serving as a cabinet member, the new agency was administered by a secretary who answered directly to the President of the United States or the national chief executive. At its creation, many touted this agency as a new security structure. This thesis argues that the formation of DHS was not innovative in nature. Rather, its formation was simply the next logical step in the tiered development of an increasingly centralized approach to policing in the United States. This development took place during the early settlement period of Texas and began with the formation of the Texas Rangers. As the nation's first border patrol, this organization greatly influenced the development of centralized policing and law enforcement culture in the United States. As such, subsequent agencies following this model frequently shared a startling number of parallel developments and experienced many of the same successes and failures. The history of this development is a contested narrative, one that connects directly to a number of current, critical social issues regarding race and police accountability. This thesis raises questions regarding the American homeland. Whose homeland was truly being protected? It also traces the origins of the power to justify the use of gratuitous violence and the casting of particular members of society as the symbolic enemy or outsiders. Lastly, this exploration hopes to bring about a better understanding of the traditional directionality of the use of coercive force towards particular members of society, while at the same time, justifying this use for the protection of the rights and safety of others. It is hoped that the culmination of this work will assist American society in learning to address the task of redressing past wrongs while building more effective and democratic public security structures. This is of the utmost importance as the United States continues to weigh the benefits of centralized security mechanisms and expanding police authority against the erosion of the tradition of states' rights and the personal civil liberties of its citizens. Because police power must continually be monitored and held in check, concerns regarding the increasing militarization of civilian policing may benefit from an objective evaluation of the rise of centralized policing as experienced through the development of the Texas Rangers and rural range policing.
