Ultimate state control
It seems to be nothing other than a universal ganging-up by the officials and the courts against this family. The implicit message is: conform with the system, or lose your child. What are the lessons to be learned? Don't ever seek help for depression? Don't leave it too late to get on the plane? Don't emigrate? Don't live in Sweden? Don't let the UK go that way.
Or is it already? Do things like that happen to people here? I know that Family Court hearings are secret and parents often ordered not to speak out about what's happening to their families.
Also, it doesn't matter where in the world they are: we're all people. We all hurt. We'd all be in agony if our children were stolen from us like that.
