Believing is Seeing: Biased Viewing of Body-Worn Camera Footage

Body-worn camera (BWC) footage is expected to be objective, thereby improving transparency. But can other information about an incident affect how people perceive BWC footage? In two experiments, we examined the effects of officer-generated misinformation and outcome information on people's memory for an event. Participants viewed BWC footage and/or read an officer's report containing misleading information. Some participants learned the officer was punished, some that the citizen was arrested. Participants then answered questions exploring their memory for the facts, the extent to which they relied on the officer's misinformation in judging who was at fault, and their impressions of the officer and civilian. Even when participants saw the BWC footage, their conclusions were consistent with the officer's misinformation. Moreover, participants' attitudes toward police predicted their interpretation of the footage, suggesting BWC footage is unlikely to be perceived objectively. We explain our results in terms of misinformation effects and confirmation bias.
