Show Me What Happened: Analyzing Use of Force through Analysis of Body

Using temporal sequencing of unedited police body-worn camera (BWC) footage of use of force incidents, we test four hypotheses to understand how incident-characteristics influence use of force, duration of that force, and the type and severity of force used by police. We code and analyze using data visualization techniques and regression analysis unedited BWC footage involving use of force in a single police agency in the United States. Use of force occurs relatively early in most interactions, though gender, race, and behavioral factors partially explain when and how much force is used. Regression results indicate that force is used more quickly against Black suspects and males. Suspect resistance predicts both time to force (TtF) and the duration of force applied. Finally, police are more likely to use greater levels of force in longer, more drawn-out interactions. Our results appear to support existing theories for disproportionate use of force, though we caution restraint in generalizing our results. We find support only at our temporal level (TtF) and do not find support for the duration or severity of that force used. These temporal variables provide additional context toward better understanding and further contextualizing use of force by police
