We live in urgent times, particularly so for those living on the Mexico border. It is like a rerun of earlier epochs: the nineteenth-century laws barring Mexican (native and immigrant) miners during the California gold rush; the massive deportation of immigrant and native-born Mexicans during the Great Depression; the moral panic about border-crossers featured in an episode of Edward R. Murrow's TV documentary series of the 1950s, See It Now. The backlash against brown residents (constructed as "foreigners" or "immigrants") comes in cycles. But this time it is even more frightening. As regimes of capital accumulation deepen global asymmetries, creating massive dispersals and displacements of entire communities, nation-states police their borders with greater aggression. In the post-cold-war era, battles are waged against civilian populations.
