Cops shouldn't see suspects as evil they the cops themselves are at war with. Formally their job is to keep the peace, get the suspect into the justice system and allow the justice system to work. Instead cops view themselves as armed enforcers on the side of "good" that the cops themselves define ad hoc.
I think you're missing the joke here, here's the relevant part of the gp:

An interesting turn of phrase, but not reality. Cops are there to enforce laws. Some of those laws are meant to protect citizens. Other laws are to protect property, protect government interests, and enforce codes of behavior. This is particularly true when dealing with mental health issues. Protection of anyone quickly becomes secondary to physically stopping the person who is acting strangely.
> Some of those laws are meant to protect citizens.
Laws are made for the just common good. They may not be ideal, but that's what they exist for.
> Other laws are to protect property,
Again, for the sake of the common good. The ability to hold private property is a prerequisite for other goods we need to flourish.
> protect government interests
What is a government interest? You seem to be alienating government and construing it as some foreign body with competing interests. No, government exists for the sake of the common good of the society it governs. Once governments begin to turn into cliques that serve, e.g., some oligarchy (quite common), esp. at the expense of the common good, we call this a tyranny.
> and enforce codes of behavior.
For the sake of the common good.

They could put the money into dealing with the social problems that cause it to be a "minefield". Their job is to protect citizens including criminals. They're not doing it properly if they're shooting people. And they're likely making people a lot more likely to shoot at them in the process.
