Research SummaryPolice brutality is a widespread phenomenon around the world. Particularly gruesome human rights abuses in the course of policing take place in Latin America, the world's most violent region outside war zones. Democratic institutions such as competitive elections, checks and balances, and judicial independence are insufficient to prevent police from abusing their power. What factors explain that police engage in abusive behaviors, including illegal arrest, the fabrication of evidence, the use of torture to extract confessions, and the excessive use of force causing injury or death? How can societies restrain these abusive behaviors and subject police to the rule of law? Police behavior is shaped by a combination of institutional, societal, political, organizational, and individual factors. Inquisitorial criminal justice institutions, inherited from the colonial past, have persisted in Latin America until very recently. This meant that democracies in the region were born with weak due process protections that have enabled state authorities and police to abuse their coercive powers as they investigate and prosecute crimes. Police brutality is further the product of security policies. High crime rates and the presence of highly organized criminal groups have pushed many Latin American governments to adopt militarized security interventions ‐including deploying the armed forces to control crime and militarizing police forces. Populist demands for harsh policies, moreover, generate incentives for politicians to adopt security strategies that violate human rights and which, in the long run, increase violence in society. The most affected groups are the poor, people of color, and those living in impoverished minoritized communities.Policy ImplicationsIt is essential to strengthen due process protections and judicial oversight over police to reduce torture and other forms of police brutality. Police demilitarization and, under some conditions, community‐oriented policing approaches can sharply reduce the use of excessive force causing injury or death. Body‐worn cameras (BWC), moreover, can effectively be used to reduce police abusive behavior —and violence against police officers — even in high violence situations and where toxic police‐community relations prevail. One limitation of this technology is that it gives too much leeway to frontline officers to turn their cameras on. Poor supervision can further undermine police compliance with camera protocols. These problems can be overcome by assigning cameras to supervisors and using more advanced technologies that allow turning cameras on from the main station. Monetary incentives that reward police officers “to kill less” is another effective policy intervention to reduce police violence causing injury or death.
