NOGALES, AZ - DECEMBER 07: U.S. Border Patrol agent Colleen Agle searches for evidence of drug smugglers in a drainage tunnel that runs under the U.S.- Mexico border on December 7, 2010 in Nogales, Arizona. A series of tunnels which run from the Mexican side into the U.S. were designed to prevent flooding, but drug smugglers frequently burrow into them to transport their product into the United States.
