A new paper released this month hopes to establish a “framework for measuring border security” that will “begin to set a base line for measuring border security between the United States and Mexico.” “Concerns about global terrorism, potential threats posed by those entering the United States illegally, and fears that skyrocketing violence in Mexico might spillover into the United States have led to dramatic policy shifts and significant efforts to secure the border,” noted the report’s authors, Erik Lee, associate director of the North American Center for Transborder Studies at Arizona State University, and Eric Olson, associate director of the Mexico Institute at the Woodrow Wilson International Center for Scholars.
