When gun-toting militants set up shop, this Arizona community got fed up and came together. Arivaca is a town of just 700 residents and sits 11 miles north of the Mexico border in a remote area of the Sonoran Desert. For about two decades, anti-immigrant vigilante groups have patrolled the region to try to remedy what they perceive as the federal government’s failure to secure the border. On this week's show, host Jamilah King sits down with journalist Eric Reidy and the town's "unofficial mayor" Ken Buchanan, to discuss how locals finally banded together to fight back, and what other cities and towns in America can learn from their success. Also in the show: Mother Jones Editor-in-Chief Clara Jeffery chats with actor Emilio Estevez about his new film, The Public.
