In July 2011, a 22-year-old woman arrived at the Calexico checkpoint on the Mexico–California border carrying a U.S. passport with a navy-blue cover. Her eight-month pregnancy and Sinaloa accent were hard to hide. A customs agent asked routine questions: where she had come from, where she was headed, and what she was carrying. Despite her answers and the document she presented, he sent her for a secondary, more thorough inspection. Other federal officers meticulously searched her belongings and the contents of her cellphones. Minutes later, once the rigorous procedure was complete, they allowed her into the country.
