Just to respond to an earlier comment about the UK and a woman worried about being 'sectioned'.
My wife has worked in the mental health field for many years, and sections about 3 people a week.
The sectioning process involves a mental health social worker, qualified and regulated in their field, a consultant physychiatrist, and a medical doctor. The section has to be approved by a magistrate (justice of peace?).
Many sections involve an armed police force because of the possibility of violence.
Sections can be voluntary or involuntary.
They are performed because the patient is a danger to themselves or to others. In a large population, there are a certain number of people who are severely disturbed. Excrement all over the walls, self abuse, drugs, psycotic episodes etc etc etc.
I have no idea about the case mentioned, but to take an example, if a mother was bleeding very heavily and an unborn babies life was in danger, but the mother refused a blood transfusion because of religious beliefs, there is a debate about whether she should be sectioned for the sake of the baby, who would die without blood transfusion. The mother can exercise choice, the baby cannot.
I would guess that if a mother is several weeks late, similar medical issues may be at stake.
If a person is already disturbed, then the circumstances can push them well over the edge and they are not in a fit state of mind to make decisions.
Does that make sense?
It is horrible work, but somebody has to do it.
I assume there are similar processes in the US.
