Unpopular opinion #2:
There's still a chance for her to change her behavior and become a productive member of society. She's young, impressionable so they're still hope we cant just all give up on the account of this one event. I say this because I have a niece who was a little gangbanging hood rat around 15-18. She and her little hood rat gals actually made national news once. And any event, she did a one year bid in juvie @18 for gun possession. After she got out she was a real change person. Now she's 24 she is a LPN, she is in the last year in college and he's doing really well.
I know as her uncle I had given up on her I just didn't think it was any way for her to turn her life around. So maybe they're still hope.
