Should I report neighbor to CPS?

We live in a large apartment building and have new neighbors. Since the day they moved in they have been screaming at their kids morning to night, the kids are always crying, there is an endless soundtrack of things hitting the floor and the walls (sounds like toys and stuff being thrown around), they are obscenely loud in common areas and generally atrocious neighbors. I've lived in apartments for more than a decade and never submitted a formal noise complaint until they moved in and kept us (and several other tenants in other apartments) awake all night with their music and screaming/slamming doors.

My biggest concern is regarding how they treat their children. They are very young, probably not even school age or just beginning school. Today I witnessed the most egregious behavior to date - the adult woman screaming obscenities at the children in the hallway including "put that motherf**g shoe on right" and "shut the f up." In what amounts to a public space...loudly. clearly not bothered by people hearing her. They were gone for a few hours of blissful silence. Then they came back home.

I muted a show I was watching because as soon as they got in the screaming resumed, and the kids were crying, and I was wondering what was going to come out of the woman's mouth. I happened to catch "you're just a dumba** little kid, you know what, f*** that."

Now they're gone again.

An additional consideration that may or may not change things: these neighbors also regularly smoke enough weed in their unit that it comes through the walls - we share no vents and it's January so windows are closed. It is STRONG. I have nothing against a little weed, but if the kids are there that is not okay.

My question for my fellow Minnesotans is: does this verbal abuse actually constitute "abuse" in the state of MN where I should consider reporting this behavior to CPS? I have not seen any evidence of physical abuse. Have any of you been in a similar situation? What have you done or what would you do? As a survivor of childhood emotional abuse I have a soft spot for these poor kids and just cringe when I think about how intense their home life is. Is there anything I can do to help?
