Just outside her front door, Tijuana resident Carmen Lopez stares into the glare of a security light looming above the U.S.-Mexico border fence. Lopez, a 63-year-old grandmother, is among residents who sympathize with U.S. Border Patrol agents. "How can they be at fault? They have a right to defend themselves," she said. Still, after Lopez's house was hit by tear gas canisters, a neighbor screamed to a U.S. agent who climbed the fence, "This isn't Iraq!"
