Neither side in an argument can find the truth when both make an absolute claim on it.

If it were simply about respecting the wishes of the family I'd be all for leaving her on the ventilator for as long as they want but it isn't that simple. We don't have a limitless supply of doctors and nurses and equipment and hospital beds. What happens when a "legally declared dead" person is supported on equipment that a "legally still alive" needs to stay alive? What happens if all of a sudden every parent/husband/wife argues that their "legally declared dead" child/spouse be left on a ventilator? And what about cost? I'd bet her medical bills are running into millions of dollars at this point. Unless they're wealthy the parents are paying for it. Is it right to force others to swallow millions in costs in an ultimately futile exercise?
