Research suggests that there is no remarkable change in the behaviour of police since wearing body cameras. Some studies suggest a decrease in complaints against the police, others show no improvements. Other studies suggest that although police initially did not like the idea of having body cameras due to fears of drawbacks in police activity, and the additional paperwork, as the programme continued police actually changed their opinion on body cameras.
One of the reasons cited is due to the fact that the police are able to hold the public accountable for their behaviour, rather than the reverse. One study revealed that in 93% of the prosecutor's offices, body camera footage was actually used to prosecute civilians. Studies have also concluded that the fear of causing a reduction in police activity and causing low officer morale, also did not transpire.
