EL PASO, Texas — For many Mexican-Americans living near the U.S.-Mexico border, the U.S. Border Patrol was viewed as a federal government agency to be feared. Its agents might raid the factory where you worked, question your citizenship status at checkpoints or detain you if an agent thought you were in the country illegally or were hiding drugs.
