A RED CAR weaves in and out of traffic on a highway in El Paso, Texas. It’s June 2022 and Texas Department of Public Safety (DPS) troopers are in hot pursuit. They are chasing someone they suspect of smuggling migrants across the southern border. The high-speed pursuit, which reaches 100mph (160kph), eventually runs parallel to the border wall. As the troopers drive closer they seem to hit the car. It flips and lands upside down. One passenger flies through a window; the others crawl out. The DPS radio traffic is mostly unintelligible except for one word. “Shit.”
