An illegal Mexican immigrant, his shirt torn by thorns while trying to flee U.S. Border Patrol agents, awaits processing at a temporary detention center in Laredo, Texas, July 20, 2001. The Border Patrol generally returns the illegal Mexican immigrants to the international bridge, the beginning of the Pan-American Highway, where they cross back into Mexico, often only waiting a few days before trying again to cross into the United States.
