Two thoughts: they should use tools like this by default within the police so the supervisors get by default alarms if their field officers do something brutal. And then you can do reporting up the whole hierarchy, how much stays unreported, which one is correct, tolerated, wrong and actually prosecuted. Could be a good way to held everyone accountable, reduce liability for lack of oversight and generally reduce the physical violence. Probably already on the work at the vendors of the bodycams.
Second, I think it is very challenging to correctly qualify some of the violence as correct or wrong. I believe this will always be a human process and the actually messy part
The assumption that supervisors would engage in disciplinary action against their officers committing such abuses of power is rather naïve considering the history of such things within of the NYPD[1]
Well, do not disagree with that, but the first thing which need to vanish is the excuse of everyone that they have no idea. And a single incident by a regular court process would be enough to fire the supervisor.
It is a tool in the end. How effective depends how you use it.
