youth in trouble - help me!!!

Today, parents of minors are legally and financially responsible for their behavior.  If a parent decides to commit
their child to therapy, a hospital, rehab, etc., the child must voluntarily go.  Even if they do agree to go, they
can check themselves out at any time.  It doesn't matter if these minors have drug addiction, behavioural issues and even
mental illness - the law as it stands now, renders us- the parents, helpless.

I would like to try to get this law changed to put the power in the hands of the parents so that they would have the authority to commit their troubled youth to a rehab (or like) facility and would restrict them from checking themselves out.
