Will we?

Ladies my brother (19) stays with us (my SO and I)and Friday afternoon, Saturaday and Sunday his gf (16) spends the night. They met when he was (18) she only comes because her prostitute mom wants to come to houston to meet up with guys. Well she buys suboxone from my someone we know and she's running my mouth saying shit like. "Oh yeah they can all get arrested if the cops go over" and shit like that. Well someone just told me and I was like wtf shes ready to go Sunday morning but he slut drug addict of a mom told her she wanted to stay to get some money and suboxone. Well his gf just left yesterday because her mom came all late for her. Instead of worrying about her daughter in school she rather go get high and dicked down for money. And when she does pick her up they never go straight home her mom goes to see guys which my brother does not like because wtf you never know what those guys she sleeps with will mess with his gf. She even told her daughter if you want to make a little money you could go with him (someone she fucks to get money a 30/40 something year old.) That she wouldn't tell my brother. Like wtf what kind of mom tells her daughter that! Well the question is can we all get arrested like she says? Also she's not a runaway and her mom even let's her stay here. She was also in the CPS system because her mom was not in the right mind to take care of her daughter. No judgemental comments! If there are some idc keep it to yourself. Also she knows I talk this about her mom because it's TRUE and she even says it. She was getting checks from her dad who passed away but it all went to the moms drug addiction. She was also saying my brother wouldn't let her leave which is a damn lie her mom just takes forever to come get her. He only doesn't want her to go if her moms not going straight home just picks her up and says oh we are gonna stay with this guy. (Her fuck buddy for money.)
