Sitting in a car late at night during in Tijuana, the mando único patrol rolls by—three vehicles of state police, federales, and soldiers. The trucks slow down to a stop. Fifteen men in balaclavas wielding assault rifles order the occupants out of the car. The officers surround them and pat them down, making a mess of the back seat and glove compartment. No one know what’s going to happen next, but after they see US passports, they ask some cursory questions and leave, this time without a bribe.
