I don't know why CPS even exists. (vent)

My sibling, who is about a year and a half younger than me, has three kids with a fourth on the way. She has no job and has expressed explicitly that she never will get a job. She basically sponges off of everyone else, including "the system".

This is the same sibling that I basically disowned because every time I talked to her, she'd scream and yell at her kids and call them names.

So I call my mother this afternoon. I haven't talked to her in about 3 or 4 weeks. She proceeds to tell me that my sibling asked her to come pick up her *expletive* grandson. This particular grandson is my eldest nephew. When she does, he tells her that he doesn't want to go home. My sibling then calls the police because my mother won't turn her son over to her. The police come and ask my nephew who he wants to be with, and he tells the policeman that he'd rather stay with my mother. (In the process of all of this, my sibling calls my mother and reams her one, saying that she was turned into CPS and she thought that my mother did it. It turns out that she didn't, but now that she's being accused of it, she will be doing it.)

My nephew then tells the policeman that my sibling punches him like a punching bag. He has the marks to prove it. My mother thinks that my second-youngest nephew was the one that got her turned in because he told his teacher that my sister refuses to let him do his homework. This is the same set of boys that said sibling has beaten with a bicycle lock chain (with the marks to prove it).

CPS has been called on this family quite a few times and there's been a lot of issues in the past with this particular part of my family. Both the father of the three boys (who is not the father of the fourth boy currently in-utero) and the mother have been found to be abusive (and my sibling even had the kids removed from the home). After hearing about what's happened, it's apparent to not only myself and my mother, but my mother's boyfriend, that the kids need to be removed from the home. It's emotionally, physically and socioeconomically abusive with the current home setting that they are all in. The same sibling has told not only myself but everyone else that she wishes they would die, that all of her problems are caused by someone else and that she wishes her kids were dead.

Yet CPS hasn't removed these kids from the home permanently?

What is the purpose of said organization if they can't do their job?!

I then told my mother that the kids need to be put into another home permanently and that the fourth child needs to be removed as soon as he's born. Then, they need to put said sibling into a psychiatric facility because a lot of us fear that one day, she will kill one of these kids. Why is it taking this long for them to place those kids with people who won't harm them or force them to live in conditions that aren't even fit for an adult human being to be in?

I fear for my nephews' lives and so does everyone else. So why doesn't CPS do their job and make sure that nothing worse can come to these kids?
