I dont think I claimed they should, the juxtaposition was the parent comment about corporations and tying that in the wider concept of law.
Corporations are legal constructions to limit liability not only of investors but of employees of the corporation, that is their function in law
Similarly the law has other legal constructions to exempt and limit liability for other positions inside that system
So it not that police are operating as corporations, the same legal construction that created corporations also created police forces.
The root of the problem for both is the same (more on that in a second)
>>it is a fundamental pillar of democracy
I disagree here kinda, a fundamental pillar of democracy is equality under the law, the root of the problem for both police, corporations, politicians, etc is the ability for the law to make some people "more equal" than others... i.e not equal at all.
This is done by making police officers exempt from some laws, some regulations, some liability even if the city is not... this is done by making individuals exempt from regulations even if the corporation is not...
So you are correct that police should not be operated like a corporation, but at the same we can look at the law and see where there are treated similarly and see why that is a problem.
I will refrain from my general negativity about democracy and just say that for what you call democracy to hold everyone must be treated equal under the law... and I do mean everyone, and I do mean equal. No exemptions, no special privileges. Most political ideologies have a problem with true equality
