Reading the articles posted to the news services yields a couple more gems that make this story more of a debate.
The daughter who herself is an RN has openly stated she doesn't think CPR would have done one bit of good in this case and that she is okay with the handling of her mother's case.
Also, this was NOT a nursing home (which is staffed with medical personnel and required by the state to provide CPR services), but an assisted living center (NOT staffed by medical personnel and NOT required by the state to provide CPR services).
Even more, the police and the reporters are not even sure the caller is in fact a nurse or medical personnel of any kind.
And finally, the police are saying they are investigating and thus far have found nothing illegal in what happened. However, several commenters on these articles have noted it IS illegal for the 911 operators to dispense medical advice, and yet they get away with counselling CPR on a daily basis.
