For decades, US governments have prioritised public security and although the prison population has begun to stabilise, the US maintains its distinction as the world leader in its use of incarceration. Crime, punishment and harsher sentences are high on the political agenda. The focus of this article however, is a movement that is challenging this view and that is gaining momentum across the US: the prison abolition movement. This movement has been studied by activists, activist scholars, criminologists, sociologists, and geographers among others, and contemporary incarceration has been analysed and theorised in a historical context of racism and slavery. Still, it is only more recently that anthropologists have shown an interest in the movement. This article aims to show, through an ethnographic example, how prison abolitionists not only in theory but concretely in practice, situate contemporary incarceration in the context of racism, slavery, and historical struggles. Drawing from discussions on meeting ethnography, revived anthropological social movement theories, and analysis by scholar-activists in the prison abolition movement, the article focuses on one specific conference in Montgomery, Alabama, in 2019.
