Analyzing how artists reimagine migrant disappearance and visibility at the US-Mexico border. In the mid-1990s, the US government implemented Prevention through Deterrence, a major buildup of troops, walls, and surveillance around El Paso and San Diego. Cut off from these crucial urban crossings, migrants flowed into the dangerous surrounding deserts, where some ten thousand have since died. This is all according to plan: Pentagon documents describe the strategy of funneling migrants toward "mortal danger." In this bracing critique, China Medel explores the aesthetics enabling and resisting the crisis of migrant death. The nation-state's performance of sovereignty along the border, predicated on mass casualties, is tolerated and even celebrated, thanks to the images in our heads of racialized and therefore criminal bodies, made invisible as they disintegrate in the baking sand. Spectral Aesthetics shows how state officials and mainstream media, relying on postracial ideologies and white-supremacist agendas, collectively foster this picture of a brown body so abject that it is disposable. In close readings of artworks contesting this murderous visual regime, Medel discovers an alternative kind of sight, one emphasizing the ghostly traces of the dead. These are images not of the individual "alien" but of life itself, indisposable.
