Surprisingly, we found that the use of wearable video cameras is associated with a 3.64% increase in shooting-deaths of civilians by the police. We explain that video recordings collected during a violent encounter with a civilian can be used in favor of a police officer as evidence that justifies the shooting. Aware of this evidence, the officer may become less reluctant to engage in the use of deadly force. We conducted more in-depth analyses with incident circumstances (e.g. whether a subject was armed) and demographics of victims (e.g. race, age), and we obtained more intriguing findings. Notably, the above-mentioned effect of technology use on fatal shootings is more pronounced for (a) African American or Hispanic victims than Whites or Asians and (b) for armed suspects than unarmed civilians.While this certainly merits further study, it seems to suggest that an officer will be less hesitant to use deadly force if he's certain that he's carrying evidence (the body camera) that will support his use of force.
Tip of the hat to Joe Huffman.
