If someone is doing something and multiple neighbors are taking note, they're the problem. I'd tip off the offender to see if their behavior changes 5-0 will make a traumatic situation out of nothing.

A lot of people don't understand how overwhelming it is to be worried about your family's safety, y'all lack perspective and empathy. If someone was slinging where I lived I'd be trying to move my family out and not everyone see that or have that option. Cut them some slack.
