If you go to them directly and they aren’t receptive, you lose goodwill (or stay at par, at best).
If you then call the cops, you lose at lot more goodwill, probably into the negative, possibly with more adverse consequences to you if someone decides you are discriminating against the partiers for some reason other than “I am disturbed by the noise”.
If you call the cops first, and they don’t know it was you, you win (if the cops shut it down).
The optimal solution is, of course, to get to know your neighbors and establish goodwill before any of this.
Absent that, I don’t think law enforcement ignoring complaints is a good solution, because many people aren’t going to be content with “there is literally nothing you can do if your neighbors are making your home unlivable.” Those people, if they can’t move, will resort to rash actions or non-state “settlers of questions”
Of course, a much better strategy is to go out of your way to be neighborly, get to know the people around you. That way if someone is having a party a few houses down, instead of calling the cops you can grab a couple six packs and head on down and join them.
Talk to your neighbors.
Definitely talk to your neighbors instead of calling highly armed and confrontational people who can kill someone or toss them in a cage because of something affecting your quality of life.
Consider talking to people and trying to understand them before you cast judgement on them. Cultural relativism really isn't that hard.
It's more risky to call a group of armed individuals with a violent history to go to your neighbor's door. Why would you ever put that sort of risk on your neighbor? The most important political relationships we can form are those with our neighbors, why would you damage those relationships by leveraging state aggression against them for something as trivial as a noise complaint?
But at least see the point of view of someone who might very legitably not feel comfortable knocking on someones door. A single person, with no family now has to run the risk of retribution with no help. Live with that fear everyday their neighbor might attack them directly or indirectly.
In fact, that's one of the first things I will do when moving into a new place, not only to socialize and build goodwill but to ascertain any potential threats and establish that I am not afraid to unload shells onto anyone breaking into my home.
In the most ghetto of ghetto places, your neighbor is the only person you fuck with. Neighborhood gangs are no joke. Only in Whiteville, America are we afraid of our own neighbors.
Decades of creating distrust in impoverished minority communities, and the government's still done a better job at keeping the affluent disunited than the poor.
