It is not at present a felony or misdemeanor anywhere for a child to play hookey. However, we somehow manage to ensure that kids attend school.
While it’s technically a form of trespass for a kid to run across someone’s lawn, I’ve never heard of a prosecution.

There are probably dozens of examples of things involving kids dealt with by police/truant officers and family court without invoking the criminal law.
Yes, a child found to be at risk through his/her own actions or the situation in which he/she finds him/herself where they are compelled to go for help.
I’m curious why we’re focusing on the girls. I’m under the impression that there are also a lot of underage male prostitutes, and that most of them ended up in that situation to escape abusive or otherwise intolerable situations at home – if not thrown out and unwilling to trust the foster care/group home system.
