It’s a game theory situation in the context of not being acquainted with your neighbors. 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”
