Book excerpt: During the late 1980s and early 1990s the city of San Francisco waged a war against the homeless. Over 1,000 arrests and citations where handed out by the police to activists for simply distributing free food in public parks. Why would a liberal city arrest activists helping the homeless? In exploring this question, the book treats the conflict between the city and activists as a unique opportunity to examine the contested nature of homelessness and public space while developing an anarchist alternative to liberal urban politics that is rooted in mutual aid, solidarity, and anti-capitalism. In addition to exploring theoretical and political issues related to gentrification, broken-windows policing, and anti-homeless laws, this book provides activists, students and scholars, examples of how anarchist homeless activists in San Francisco resisted these processes.This book is relevant to United Nations Sustainable Development Goal 2, Zero hunger.
