A 2015 Journal of Criminal Justice article found the following:
- Body-worn cameras are effective in reducing response-to-resistance incidents by 53.4%.
- Body-worn cameras are effective in reducing serious external complaints by 65.4%
- Body-worn cameras improve evidence collection and report writing
The general study was based on the Orlando Police Department. The study consisted of measuring the “response to resistance” consistent in varying arrests and police procedures. The study found that an “Overwhelming agreement was also found among officers who wore the BWCs for the utility of BWCs to improve evidence collection and report writing and improve their behavior and police work in general by having the opportunity to review their own BWC videos.”
