How can policymakers reduce public fear of crime in Latin America? This study compares the effectiveness of “zero tolerance” and community-based policing strategies in Argentina, Brazil, and Chile. At the micro level, it assesses the links between fear of crime and social identity characteristics, contextual factors, the media, community participation, and other insecurities. It finds that citizens' economic, political, and social insecurities are the main determinants of their fear of crime. At the macro level, the study compares levels of public insecurity and finds that cities that employ community-based strategies to fight crime register lower levels of public fear of crime.
