Public Perceptions of the Justifiability of Police Shootings: The Role of Body Cameras in a Pre- and Post-Ferguson Experiment

Abstract

We conducted two studies, wherein participants from across the United States watched, heard, or read the transcript of an actual police shooting event. The data for Study 1 were collected prior to media coverage of a widely publicized police shooting in Ferguson, Missouri. Results indicated that participants who could hear or see the event were significantly more likely to perceive the shooting was justified than they were when they read a transcript of the encounter. Shortly after the events in Ferguson, Missouri, we replicated the first study, finding quite different results. Although dissatisfaction with the shooting was seen in all forms of presentation, video evidence produced the highest citizen perceptions of an unjustified shooting and audio evidence produced the least. Citizens were nonetheless overwhelmingly favorable to requiring police to use body cameras. Body-mounted cameras with high-quality audio capabilities are recommended for police departments to consider.
