Physical insecurity and high rates of crime plague Latin America. The problem is economically costly, detrimental to physical and mental health, and damaging to political legitimacy, while also fueling a migration crisis and negatively impacting societal views on human rights. The police are tasked with responding to and investigating crime, but have been historically ineffective at doing so. In recent decades, many countries in the region have implemented significant police reforms in pursuit of decreasing crime and insecurity. This thesis will analyze reforms in Brazil, Colombia, Chile, and Mexico to determine regional themes of reform. The lessons from those case studies will then be synthesized into a list of eight implementable and generalizable policy recommendations.
