In my mind, the issue is that the government is not the parent, and the parent gets to choose. I could see the hospital refusing medical care or the insurance company refusing to cover something, but that isn't the right to keep the child incarcerated.
This case stinks. The girl ended up in this state after tonsil surgery. How do I know the hospital and insurance company aren't protecting their financial interests?
Again, the parents aren't fighting to take her home. They're fighting for her to continue receiving hospital care.
