Protesting police use of force - George Floyd protests in Chicago

What we do Heading link

The deaths of George Floyd, Breonna Taylor and so many others have sparked outcry around the world. But most cases go unrecognized by the media and general public; every day in the United States, people like Floyd and Taylor are injured or killed during law enforcement activities. While police activities broadly impact many lives, Black men are far more likely to be stopped, detained, arrested, injured and killed by police, which has been a key driver of the Black Lives Matter movement and calls for police reform which date back more than 100 years.

Our Law Enforcement Epidemiology Project aims to build a comprehensive surveillance system to better characterize the magnitude of civilian and law enforcement injuries that occur each year in the U.S. and to guide policy reform that addresses police use of force tactics and strategies to build community trust in the police.

Project Goals Heading link

We aim to provide surveillance data for the U.S., Illinois and Chicago on civilians injured during interactions with law enforcement and officers injured on the job. Because comprehensive data on civilian non-fatal and fatal injuries caused during interactions with law enforcement is lacking in the U.S., this site primarily focuses on civilian injuries.

  • Reporting

    Identify barriers to reporting.

  • Analysis

    Describe long-term impacts on individuals following an injury caused by law enforcement personnel.

  • Recommendations

    Develop policy recommendations for police reform.
