<human>: Can you condense the text into a few key points?

My husband and I have lived in our neighborhood for about 4 years now. The people across the street from us are horrible. They're the definition of White Trash, and this is a nice little family neighborhood. It's not the owner of the house that is horrible. He's a nice little old man, it's his daughter that's obnoxious. 
Anyway, since we moved into our home I've listened to this woman SCREAM and SCREAM at her young children, (She has 4 kids, 1yr, 3 yr, 4yr, and 9yr). I have thought about calling DCF many times over the years, but I've never seen her physically abuse the children and I don't know if cussing at them, screaming at the top of her lungs and such are reason enough to have her investigated.
She screams things like, "What the fuck is wrong with you?! Are you completely retarded??? Get your dumb little ass in this house NOW!!!" to her 3 and 4 year old children constantly. She also screams at the nine year old, and if the baby starts crying she will just yell like "AAAAARRRGGGHHHH!!!" at the top of her lungs back at the baby. 
But like I said, to me this seems like emotional/mental abuse. Can the Dept of Children and Families do anything about that?
I know that it's anonymous, but I just don't know if they'd be better or worse off in the system and I'm not sure it's any of my business in the first place...I'm just so worried about those kids.
The oldest one has started bellowing like her mother now at the little ones. So what does Reddit think? Should I make the call? Or mind my own business?
<bot>: Neighbor is constantly screaming profanities at her 4 little children, so loudly that I can hear it from inside my house when she's inside her house (windows open though). Should I call DCF? Or mind my own business?
