Arquitecto Tucci, a neighborhood in Buenos Aires, is a place where crushing poverty and violent crime are everyday realities. Homicides—often involving young people—continue to skyrocket, and in the emergency room there, victims of shootings or knifings are an all-too-common sight. This book takes a harrowing look at daily life in Arquitecto Tucci, examining the sources, uses, and forms of interpersonal violence among the urban poor at the very margins of Argentine society. It provides a powerful and intimate account of what it is like to live under the constant threat of violence. It argues that being physically aggressive becomes a habitual way of acting in poor and marginalized communities, and that violence is routine and carries across various domains of public and private life. The book traces how different types of violence—criminal, drug related, sexual, or domestic—overlap, intersect, and blur together. It shows how the state is complicit in the production of harm, and describes the routines and relationships that residents, particularly children, establish to cope with and respond to the constant risk that besieges them and their loved ones.
