Where the US already has a border wall

Nogales, Arizona, and Nogales, Sonora, are known as “Ambos Nogales” — “both Nogaleses.” The city straddles the border of Arizona and Sonora, Mexico. For a long time, a hole-riddled chain-link fence ran along that border. Residents could cross back and forth with ease. But in 1995, the federal government replaced the chain-link fence with a wall. Over time, that wall has been fortified with surveillance towers, more Customs and Border Patrol agents, and drones.  President Trump wants to extend the Nogales model all along the US-Mexico border. In the final episode of the season, The Impact goes to Nogales with the Arizona Republic to find out why the federal government decided to build the wall, how it has changed Ambos Nogales, and how it has affected migrants who hope to cross into the United States.
