I think I get what you're trying to say, but it's important to stress that the organization of the police are an entity specific to Capitalism. They didn't exist before and they won't exist after, in fact they'll be the very first thing to go during any kind of Socialist uprising https://twitter.com/hasanthehun/status/1299030489391435776

As far as 'upholding order' goes you're right yea, *something* is necessary, and the term you're looking for here is a people's, or proletarian, milita. The role of 'keeping peace' is sublated back into the general armed population rather than held in a special body of armed men.

I have a video on this topic specifically coming out at...some point, so look forward to that
