It always has been in America. Literally, the history of policing starts with armed gangs looking for escaped slaves, and never went away from those roots. You can see this in their "us or them" combative mentalities, their utter refusal to hold officers accountable even when obviously guilty, their tactics when governments try to impose rules on them, and everything else they do.
“A gang is a group or society of associates, friends, or members of a family with a defined leadership and internal organization that identifies with or claims control over territory in a community and engages, either individually or collectively, in illegal, and possibly violent, behavior, with such behavior often constituting a form of organized crime.”
I’d say that fits some law enforcement pretty well.
