"Illegal cross-border activity is a severe homeland defense and security problem along the international Southwest border. The issue of illegal human smuggling is not new to the United States-Mexico border, or to law enforcement agencies; however, the phenomenon continues to increase while smugglers adjust to law enforcement tactics. This paper is a synopsis of the thesis entitled 'Modeling the U.S. Border Patrol Tucson Sector for the Deployment and Operations of Border Security Forces' which describes and identifies the fundamental dimensions of U.S. Border Patrol operations in the busiest, most vulnerable section of the border. This paper seeks to provide a comprehensive picture of the complex dynamics along the U.S. Border Patrol Tucson Sector and highlights the primary challenges facing policymakers in developing innovative policies that will minimize illegal cross-border activity and secure the homeland."
