In Canada what can often happen (although it is never directly admitted) is that the morphine drip (or other condition) is changed so that a peaceful death results. How do I know this? Because my father was a doctor.
Mind you I am talking about a hospital environment.
Are there similar conditions that might exist in the US? Perhaps you could inquire in the most indirect and subtle manner by visiting the various hospitals etc and dialoging directly and separately with each of the caregivers that might have such influence.
As to this specific circumstance, again you would need to inquire (in the most indirect and subtle manner) by dialoging directly and separately with each of the caregivers that might have such influence.
You are looking for a sympathetic ear!
Two sections of Canada's Criminal Code are relevant:
"14. No person is entitled to consent to have death inflicted on him, and such consent does not affect the criminal responsibility of any person by whom death may be inflicted on the person by whom consent is given.
"241. Everyone who counsels a person to commit suicide or aids or abets a person to commit suicide, whether suicide ensues or not, is guilty of an indictable offence and liable to imprisonment for a term not exceeding fourteen years."
The reality of modern medicine is that doctors do practise passive euthanasia; not all of them, but rare is the doctor that has not, at the request of the patient, the patient's family, or on his or her own accord, decided to discontinue life-support.
