, you're in B-field? We just went through there going back to Fresno from LA, stopping at Dewars. Small world!
Back on topic, Alidar
would be useful, since I've managed to forget most of what I learned in law school. But as noted by a poster above, no duty to help a stranger exists unless a special duty exists or you created the danger.
In this case, there is (as usual) conflicting information in the news: there is a DNR on file, there isn't; there's policy against CPR, there isn't; this was a skilled nursing facility, it was a communal living center not providing medical care; etc.
There are lots of questions, including whether the woman/family aware that the lack of medical care included no CPR under emergency situations--but this may be negated by the fact that (supposedly) the family has stated that they and the woman were aware of this and it was fine with them. It appears there's no case here as only the family is a party with standing to sue. Dont blame all lawyers: Decent lawyers don't troll for clients; blame the clients' greed--and shitty lawyers who agree to take them on.
A positive outcome would be legal clarification of the status of the various types of elder-care facilities and their respective duties to the persons staying there, and their families. Now, likely, this would be on a state-by-state basis, which different laws in each state, because such facilities appear to be state-regulated, not federally-regulated. I believe there are some federal laws regarding elder care, but I know nothing on the subject.
