US border patrol

A U.S. border patrol vehicle is seen from the Mexican side of the border while driving near Otay Mountain on the outskirts of San Diego, California June 6, 2010. In response to spiralling drug violence in northern Mexico where cartels are battling for smuggling routes, President Barack Obama announced he would send 1,200 more National Guard troops and ask for an additional $500 million to secure the almost 2,000-mile U.S.-Mexico border. [Photo/Agencies]
