Should i call the police to set my younger sister straight with her behaviors and make her understand its not a joke?

I completely agree with yall. she needs consistency and discipline and that is something my mother doesn’t do or allow. Its extremely exhausting dealing with her 24/7 especially since im the one who makes sure she is taken care of and clean being that im only 17. And for the things we do we get nothing but disrespect from her, and i cant be a parent roll w/o the discipline part. And at this point me and my older sister dont know what to do with her. But her almost breaking our dogs arm because she was mad is absolutely not going to be tolerated ESPECIALLY since she thinks its a joke when we yall at her for it including my dad who punished her for it. Honestly i do think she needs professional help considering this isn’t her first time doing this (she tried to kill other pets when she was younger) and with my mom in the way thats not gonna happen. im very concerned for her but i do appreciate all y’all comments. Considering yall are law enforcement is there a way i can get her professional help w/o my moms approval
