If that is textbook police work, then the textbook is a piece of crap and needs replacing, because you can see from the start how he is failing to pick up the fact that he is triggering escalation step by step for no good reason.

If you find it offensive that some people actually expect the police to treat people with empathy and understand they may be dealing with scared and panicked people or people with mental health issues, then I have no sympathy whatsoever.

The police exists to serve, not to scare innocent people into staying home - at the moment that happens, the police has become the problem and needs to be dismantled.
