. . .and as long as it's a California court deciding what is and what is not negligent, I'll take Martin's advice. From what I read, a better course of action for the girl who did the negligent rescuing would have been to do nothing, so that is what I intend to do.
That's true irrespective of the legal situation, though. I mean, the bad outcome here is that the victim got paralysed. You wouldn't want to intervene in a way that paralysed someone even if you didn't think they'd sue you for it afterwards.
