Article Photos: What does a 'secure' border look like? 5/8

FILE - In this June 19, 2008 file photo, U.S. Border Patrol agent Santos Flores walks in front of a section of old border fence, left, where it meets a five-mile section of new border fence  at the border in Nogales, Ariz. New fencing, more agents and a state crackdown have help drive down the number of illegal immigrants apprehended, but the amount of drugs seized in Arizona has soared at the same time.
