My question involves juvenile law in the State of: California, LOS ANGELES COUNTY
My question is as follows,
I am currently 20 years of age and my friend from high school is 17, soon to be 18 in about 5 months. His parents are insane, the mother has this verbally abusive personality and will get ghetto with anyone who questions her opinion and stance and his father is a puppy dog that doesn't have control over his emotions and will often times resort to physical threats. One day she's nice, the next she's really loud and nasty. (More like morning to night) and she is currently on anti-depressants.
I try my hardest to get along with them but they make it seem like it's a competition to gain his favor, which is ridiculous cus the parents are my parents age.
Whenever he can't handle the stress of that household, he reaches out to me for comfort and guidance and often times I remove him from the situation which results in her acting ghetto and saying that she is going to call the police on me. She will constantly call me to the point that my mother said to block her number, she will threaten me with a restraining order, she yells at me, the dad will threaten me. I mean, I am seriously not at ease with the sight or even when hearing her voice. It's that bad, but I care about my friend too much to back off, especially when he needs me and begs me to help him or pick him up.
In this case, I don't care to make my life any more hectic and want to avoid all drama with courts or whatever (but still stand firm) and help my friend out.
What can I do? [AND] am I at risk for getting in trouble for plainly helping my friend out?
