I'm not sure how this would make calgoo change his mind.
* Cops are under no obligation to go into harms way to protect the public.
* Cops primarily exist to collect evidence for prosecution after the fact.
* Just because criminals and crimes exist doesn't take away from cops' bad behavior.
* If calgoo becomes the victim of a crime, cops are unlikely to be able to make him whole again - for bodily injury, prosecution of the perpretrator can't restore his body or life - for property damage or theft, police usually can't be bothered with the small stuff.
There are problems with power and corruption.... But
Have you seen what happens to communities when police withdraw? They become overrun by gangs and other less accountable organizations.
Even favelas where cops act paramilitarily, say in Caracas, people still want cops because no cops is usually worse, unless you get a private version of cops, which is essentially cops by another name.
Not to disagree with you, but to add a data point (or rather an anecdote) - I heard a few people from Moscow claiming that they're more afraid of cops than criminals.
(Of course, even if it's not an exaggeration and even if it reflects the actual probabilities of getting hurt by cops and criminals there, it does not follow that things wouldn't be even worse without a police force.)
