With this action of self policing it become Black Panthers redux. Without accountability like the police they have a high probability to turn into petty tyrants that the Panthers became.
In all fairness, part of the problem is that the police are much less “accountable” than they should be - too many bad apples are protected by the contracts, unions, and in many cases politicians.
This will be a major step to tribal rule in many urban settings, IMHO. Whatever the head of the overseeing organization says will happen will be forced to happen.
Meet the new boss, same as the old boss.
