STUDY OBJECTIVE
Results from a global, multisite randomized controlled trial on whether body-worn camera use reduces citizens’ complaints towards the police.
TREATMENT
Police officers who were randomly assigned to the treatment condition were required to wear a body camera during their shift.
CONTROL
Police officers assigned to the control condition were not required to wear a body camera during their shift.
MAIN RESULTS
1) The number of complaints lodged against the police dropped in the post-treatment period from 1.20 to 0.08 complaints per officer, marking an overall reduction of 93% in the incidence of complaints when police wore body cameras.
2) No difference between post-treatment group and control group on police complaints. These results can also be read as a no-differences in the odds of a complaint lodged against officers during a treatment shift, compared with the odds of a complaint filed during a control shift.
