she bullied, stalked, cyber-stalked and harassed another girl. that would be a crime (a misdemeanor?) for an adult. she's a child so she needn't be treated like an adult, but she can be processed thru the juvenile court system where she would be evaluated and recs made. yes, I do have faith in the juvenile system and mental health professionals who work with these teens and their families.
This is the sensible answer.
You have way more compassion than I do. I'm too mad to even think about the very real possibility that these girls need help.
I have faith in mental health professionals, too. There are bad ones, like every other discipline, but there are also good ones, even great ones, too.
