The impact of Body-Worn Camera on criminal justice outcomes of domestic abuse incidents

The trial was completed by a total of 308 officers; 70 of which were randomly allocated cameras for use, the rest remained without to act as a control group.

Key findings


  • The trial showed that issuing officers with body worn video could be effective at increasing the proportion of detections that resulted in a criminal charge.
  • There were no differences in incidents being recorded as crimes, or rates of arrest, and too few cases to identify impact on guilty pleas and sentencing at this time.
  • Officers with BWV frequently mentioned the evidence gathering benefits of the cameras. They also reported feeling confident that incidents they attended would result in convictions.
  • Most officers surveyed stated that they did not switch the camera on for every domestic abuse incident and there were practical issues that limited the possible benefits of the camera.
