<human>: My boyfriend and I live in a shotgun-style apartment with eight apartments in the building. We live in a good neighborhood --- poor, but with lots of families and everyone is friendly and kind. The neighbors I'm worried about are the ones whose apartment shares a wall with the hallway that runs the length of our apartment. They're a man and a woman, late twenties to early thirties, and a boy who's probably four at most -- her son, not his, we think.

A couple of months ago, they started having terrible screaming matches at all hours of the night and sometimes midday. Whenever we heard them start up, my boyfriend and I would get very quiet and listen carefully to make sure no one was being hurt. It started as worrisome and quickly became juvenile and annoying. At one point she followed him out to the dumpsters under the windows on our side of the building to continue berating him. It was honestly pathetic.

My level of concern went from passively annoyed to seriously troubled this afternoon, though, when we witnessed him buying drugs that were definitely not pot from some dude in a car in front of our building. I know he knows that we saw him, but I'm starting to feel unsafe. Between the fighting and the drugs, I'm starting to wonder if I shouldn't put in a call to child protective services or the police. But I'm also nervous that they'll figure out it was us who put in a call and try to fuck with us.

What should I do? Can I even do anything?  I emailed our landlady to let her know what was up.

Can you condense the text into a few key points?
<bot>: our fighting neighbors have bought drugs, and her kid lives with them.  They know we know.  I want them out and the kid in protective custody, but I'm worried about potential repercussions.
