November 25, 2020—Through the cooperation of more than 50 of the largest law enforcement agencies across the U.S. and Canada, our research team was granted access to the most detailed dataset ever collected on fatal and non-fatal shootings by officers while on duty. Covering the period from 2015 through 2018, these data cover over 1,000 fatal and nonfatal shooting incidents, including characteristics regarding the reason for and circumstance of the encounter, the location, and the officers and the other individuals involved. While differences in data availability and policies impacted our ability to collect every detail across all agencies and incidents, the data provide important insights on these statistically rare, but massively important, events. In particular, the data shed light on an often overlooked aspect of the events that likely contributes significantly to the problem and yet remains understudied and unaddressed.
Although traditional and social media content may lead some to believe that officer-involved shootings most often begin with encounters involving a traffic or vehicle stop, our data reveal that in the large agencies we worked with and those providing sufficient data to assess the origins of these incidents, over half of these events began with a community member calling 911. Slightly less than half of the encounters began by an officer-initiated activity (e.g. initiating a traffic stop).
