Here is a short claim on the importance of police wearing body cameras:
The average person will behave better if they know that there is some level of accountability for their actions. When there is a noticeable camera present on the uniform of a police officer, then the interactions between the public and law enforcement officials typically become more civilized. Because the footage can also be useful as evidence if a case goes to trial, many suspects calm down from an initially aggressive response because there is an increased risk of more charges based on the direct record of their activities.
Some officials may bristle at the idea of adding something else to do, but the cameras used as part of their duties are not cumbersome, bulky, or obtrusive to the work being performed. Most of the devices work well with the existing uniform so that one hardly knows it is there.
I hope this helps, have a great rest of your day! <3
