Skip revolution. Just change the damned laws so that placement out of country triggers custody hearings, and placement in country requires both a court order, with the teen represented by a family and childre's services caseworker AND a psychological/psychiatric evaluation of the parent(s) and/or all adults living in the household with the teen. If significant mental troubles on the part of one or more of the adults is found, allow the teen to opt to try foster care FIRST.
Also, evaluation triggering court order must be with court appointed expert, not parent-selected expert.
Make criteria for commitment and of [ a) imminent danger to self; or b) imminent danger to others; or c) delinquent behavior ] AND setting is least restrictive option necessary to provide treatment.
IOW, except for c, the same criteria for involuntarily committing an adult.
Provide that kidlet has to be transferred to least restrictive setting as soon as imminent danger that triggered commitment is stabilized.
Make failure to adhere to standards on part of parents count evidence parents are unfit, so even if authorities wink, wink, nudge, nudge and let the parent get the teen there, other relatives can fight them for custody.
