On Wednesday, January 9, TBI Director David Shirk provided a briefing to the U.S. Northern Command (NORTHCOM) on recent developments in Mexican security. The briefing took place at NORTHCOM's facilities in Colorado Springs and included high-level analysts from the Department of Defense and other U.S. government agencies. The title of the briefing, "The Drug War in Mexico: U.S.-Mexico Security Challenges in 2013 and Beyond," provided an overview of the recent findings of the Justice in Mexico Project, sponsored by a generous three-year grant from the John D. and Catherine T. MacArthur Foundation. Specifically, the presentation included new data from the institute's forthcoming report on drug violence in Mexico, as well as a discussion of Mexico's changing security context under newly inaugurated President Enrique Peña Nieto. The presentation used for this briefing is available in PDF form.
