Research objective: This study aims to evaluate the impact of body-worn cameras (BWCs) on the number of deaths resulting from police intervention by the Military Police of the State of São Paulo (PMESP) and to investigate whether BWCs affect police proactivity in situations characterized by a high risk of confrontation.
Theoretical framework: We used the Theory of Planned Behavior (TPB), which informs that human behavior is guided, among other factors, by an individual’s perception of the likely consequences (positive and negative) and social expectations of a given behavior.
Methodology: We utilized the differences-in-differences statistical method to estimate the effect of BWCs on deaths resulting from police intervention and firearm seizures, using data provided by PMESP.
Results: Statistical analyses indicate a significant reduction in deaths resulting from police intervention in battalions that implemented BWCs, as well as a possible decrease in police involvement in high-risk situations, as evidenced by a reduction in the number of firearms seized. Mediation analyses suggest that 29% of the decrease in deaths due to BWCs can be attributed to a decrease in police proactivity in these situations.
Originality: This study offers new insights into the impact of BWCs on the use of force, as well as the role of reduced police proactivity in high-risk situations as a possible explanatory mechanism.
Theoretical and practical contributions: The findings contribute to the understanding of BWCs' effects on the behavior of military police and provide useful information for decision-makers in the public security field.
KEYWORDS: Body-worn cameras, São Paulo State Military Police, Deaths resulting from police intervention, Use of force.
