Discussion
Ariel and his colleagues carried out a study to determine the effectiveness of using body-worn cameras in recording incidences of police use of force on civilians. The research was carried out in a randomized controlled setting in a period of 1 year. The research was carried out in two phases; the first phase was an experimental shift where the police officers were provided with body-worn HD cameras that chronicled all their activities and interactions with the public. The second phase involved the control shifts where the officers were not provided with cameras. The authors technically elucidated the use of force -needless and rational, as an unwanted reaction in the encounters between the police and the public. The research projected the primary outcome of utilizing body-worn cameras on two resultant variables by using Poisson regression (between-group differences) and interrupted time-series analysis (before and after estimates). The findings indicated that the police use of force was higher in the control-shift group without cameras and lower in the experimental-shift with cameras. The authors concluded that police body worn cameras are effective in minimizing the use of force on the public by the public. The findings were discussed in terms research methods, theory, and future effects.
