Well she doen't look 'brain dead' to me! Who says her brain is 'mush'? What sort of diagnosis is that? Yours presumably. When I saw her on tv over the last couple of weeks, She clearly recognised her mother/father and had a significant capacity to communicate using her eyes. She also moves her head and seems to follow what's happening around her. This woman isn't brain dead and she is not in a PVS (in my opinion).
This decision to withdraw food, in spite of her parents' willingness to look after her, smells like someone's convenience.
