Just a month ago, Homeland Security Secretary Janet Napolitano told a Senate committee the US-Mexican border "is as secure as it has ever been."

The National Guard will help law enforcement target the smuggling of drugs, guns and people, but not by making arrests or intervening directly. That's according to Ken Dilanian, who reports from Washington for the Tribune Company.
