I have watched many "accountability" videos, including the one in the OP (prior to seeing it here). If there is one thing I have learned from all those videos, it's that there is a terrible culture of entitlement and misguided assumption of authority among police that is not backed up by statute. The utter rejection of people's Constitutional rights for (both in the US and elsewhere) is appalling. Frankly, I think that
officers who abuse their position should be held to the same standard they hold suspected criminals: guilty until proven innocent. No "paid administrative leave", no "reassignment pending investigation", no quiet cover-ups by the "thin blue line".
However, I also have friends who are or were police officers. There are many good officers who fulfill their responsibilities with humility and integrity. I won't speculate on which is the majority.
Policing, like much of our culture, is broken. It isn't going to be fixed by bashing and decrying, but if police officers knew they would lose their jobs, be sued personally, or be jailed if they abuse their authority, they might rethink how they treat people when on the job, or in the case of the OP, how they act when off the job.
On a related note, any system that uses quotas (or any form of incentive) for certain offenses is abuse looking for a place to happen. Power corrupts.
