Although this is regarding the age of consent, it also applies to the formentioned subject.

One could be accused (after encouraging emancipation) of actions that arent in the best interests of the child. If you find yourself in a situation where the child is at risk, I suggest you encourage the child to keep a 'journal' of sorts and seek help from a school counsellor or something, stay invisible.

Contributing to the Delinquency of Minors:

Most every state has such a statute, which can be evoked in cases where the age of consent statute was met, but other circumstances warrant an arrest.  For instance, it may be legal for two people to have sexual relations by law, but the fact that one kept the other (under 18 for example) out too late while having sex might subject the actor to arrest.  This is the catch-all statute.  Often used when parents can't get a boyfriend on age of consent/statutory rape charges, they find a way to use this statute to cause trouble.


Read this Example from Nevada (actual law):
