Body cams have been recently been distributed more broadly across the police force everywhere across the United States. This is thanks to the recent events of so called police brutality and the anti police crusade by groups such as BLM. There is no denying that with as many cops there are in the United States along with the power they hold in their hands, that some of them will abuse this power.
Body cams benefit both the citizen and the police officer. If the citizen is law abiding and gets wronged by a cop, then the body cam will give evidence to their innocence. If the cop is following protocol and gets wrongly accused by the citizen, then the body cam footage will clear them. These cameras are only disliked when the person disliking it is obviously doing something wrong.
