Policing to Promote the Rule of Law and Protect the Population 
An Evidence-Based Approach

The U.S. Department of State, through its Bureau of International Narcotics and Law Enforcement Affairs (INL), provides foreign assistance and supports capacity building for criminal justice systems and police organizations in approximately 90 countries around the world. It has a mandate to strengthen fragile states, support democratic transitions, and stabilize conflict-affected societies by helping partner countries develop effective and accountable criminal justice sector institutions and systems.While the science of policing outcomes has grown in recent years, it is limited in context, with much of the research conducted on policing taking place in the Global North countries (e.g., the United Kingdom and United States). It is also limited in purpose, with much research focused on examining crime reduction as opposed to examining the harms to the public as the result of crimes, violence, and any effects of policing activities.At the request of INL, Policing to Promote the Rule of Law and Protect the Population explores the organizational policies, structures, or practices (e.g., HR and recruiting, legal authorities, reporting lines, etc.) that will enable a police service to promote the rule of law and protect the population. This report presents an overview of the state of research and highlights promising areas to guide policing reform and interventions.
