Not sure what there is to elaborate upon.
Allowing law enforcement to maintain a default stance of antagonism - “us vs them” - can only lead to law enforcement being leveraged by those in power (political or capital power) to define who the “them” is.
I’d much rather have law enforcement have a default cooperative stance with their communities and society at large. You know, if “protect and serve” wasn’t just a marketing gimmick but an actual principle applied during process and procedures.
In essence: thin blue line is an illiberal aesthetic that has 19th century American leaders rolling in their graves - at least the ones who weren’t chasing down slaves to return to the South.

Hmm. Interesting. Function may be an emergent quality of the organization itself ( as human I have two hands, as octopus I have more appendages to play with ). In other words, the question is not really on what you personally would rather have, but what a given body type bestows upon a given organizational type.
Your body determines your function oversimplification for the purposes of this argument.
