I got tired of calling the cops and was close to hurting the low life. What I did was move to a more expensive area where people had more brains and respect for each other.
Some people are also missing the point, as a lot of people think they are required to give their names and addresses to law enforcement when they make a complaint, as they always ask for personal information like name and address. This could have been one of those people that was afraid of retribution or retaliation if he called the police.
And besides, people who get the cops called on them generally always know who did it, and they are generally right. Like at this party, if people from apartments on both sides of the party apartment were in attendance, the likely person to call the cops would be the one that lived directly above the party apartment. It's generally not hard to figure out who the cop callers are.
