(Anti-Riot)Police see themselves as the entity that establishes order at the cusp of disorder.
When you have these kinds of confrontations (it could be internecine for all I care) you’re going to see that kind of human interaction. Neither person is a robot and thus the results are less than ideal.
What is worse is a power vacuum and the resulting gangs and warlordism (unless the community stands up its own local police force) but we’re back to policing.
