Police Quarterly Dated: 2020
Because little is known about law enforcement officers' perceptions of body-worn cameras (BWCs) and whether officer perceptions change following implementation within their agencies, the current study used data from an evaluation of BWCs in the Phoenix Police Department (Arizona) to examine officer perceptions of the utility of BWCs, perceptions of organizational justice, and support for using procedural justice.
The study used inverse propensity weighted difference-in-difference models to examine changes in officer perceptions over time between randomly selected officers who were mandated to wear a BWC, BWC volunteers, officers who resisted BWCs, and control officers. The study found limited significant differences in officer perceptions of BWCs over time, although effect sizes suggest that BWC volunteers and officers mandated to wear BWCs were more subdued in their expectations about BWCs at the post-test. 62 references (publisher abstract modified)
