Valeria Luiselli first travelled to the U.S.–Mexico border in 2014, when the current immigration crisis began to heat up. Under the Trump Presidency, the border has become the dead center of American politics, and Luiselli returned with the radio producer Pejk Malinovski. Luiselli is a Mexican writer living in New York, and the author of “Lost Children Archive” and other books. She wrote in The New Yorker about Wild West reënactments, in which actors stage scenes like a gunfight at O.K. Corral. In Tombstone, Arizona, and Shakespeare, New Mexico, she finds a very particular view of Western history that elides the U.S.’s long and complicated relationship with Mexico, which once owned this region. She finds that historical reënactments feed a notion of the border region as a lawless frontier requiring vigilantes to defend American interests.
