Hmm.. Puzzling.. So they had info on this bear, medical info, and very probably knew she was aggressive.
So....here comes a multi-million dollar lawsuit by the family of the deceased. Issue: Mr Park Ranger, you obviously knew this was a deadly bear and you did nothing about it. Ruling: For the plaintiff; reward the family a few million dollars.
Wilderness areas and National Parks shouldn't be viewed as Disney adventure parks IMO and that is becoming the norm more and more. The animal makes its choices, however ignorant they may be in making them, and suffers the consequences. Humans make their choices and ought to bear (no pun intended) the consequences for them too.
