So freaking sad... my heart hurts

So the other day I was at work and all the sudden I hear my co worker screaming for help and another lady. I came running out fearful for my coworker because once in a blue moon we get really nasty customers. Well it's this lady maybe mid 20s (hard to say because you can tell she uses) she's screaming for our help because her mom was getting beat up and I guess the daughter got hit from behind. We all go outside and there's 3 ladies trying to fight the mom in the middle of the street. What I noticed was there where also 3 kids in the street as well. Two baby girls 2 and 3 and I think a 10 year old. All I hear is them screaming about a guy and them owning said guy money. You could also hear the babies crying calling for mom. Again this dumb batch was more worried about her mom and herself... All I could focus on was the kids. That's when I turned to her and told her to go get her facking babies and worry about your mom after. Again both mom and daughter looked like they where on drugs. She yells for the 10 year old to bring them and was back to talking about her and getting hit. All while the poor babies kept asking for her. Not once did she try to comfort them or anything. That's when my coworkers and I started to talk to the babies and try to calm them down. The younger one was a little upset but it also felt like this was just the norm her her. The 3 year old was frantic and just kept calling for her mom. I can't tell you how much I wanted to pick them up and tell them it will be okay. Even if that okay was a lie. They where both under dressed and dirty. And I'm not talking a little food on the face. Dirty clothes, hair everything. The cops showed but the other ladies took off. No one was caught. As I was leaving I saw them go into a trailer park running and screaming. It was just heartbreaking. I called the cops again and told them where to go on a possible fight and child endangerment. I wish I would of followed them but at the same time I didn't want to be caught in a fight. I have my own safety to worry about and my girls at home who need me. I pray the cops showed and did something more. It's shat like this that makes my blood boil. How could you not care about your children? How can you let them be dirty and under dressed all while they had jackets on and at least looked showered. The 10 year old just stood there like its no big deal. It seems like she too is use to this BS. Sadly there's to many children in this type of situation. I hope I see them again so I can figure out where they stay and call CPS. I'm not one to call CPS unless I feel it's truly needed. No child should go into the system but I feel that's 100x better then being around a bunch of low life druggies. What if these chick went after the kids? What if a car hit them? So many what if's and I feel so powerless. I went home and hugged my kids over and over. I'm greatful I'm sober and do my all for them. I'm a recovering alcoholic got sober 6 years ago. I know what it's like but I also got sober to be the best mom I can. Luckily I never did anything close to what those women did. I just know I'm a person that can't drink and being sober is the best gift I can give them. I know what addiction can do and how selfish it makes you. I hope they wake up one day and get it together not only for those kids but themselves.
