As I think about this story there are a few things that come to my mind:
1. It would be horrible to see people become less willing to try and help someone in need.
2. The 'rescuer' was out of her mind moving her friend who couldn't move for herself. That just screams leave her in place and I am not even in the medical/EMT field. Isn't it just common sense to not move an injured person unless absolutely necessary? This business of the car being on fire doesn't hold water with me as the other witnesses reported there was none they saw.
3. I can't wrap my brain around why the injured friend is suing. Yes, she is paralyzed and that sucks massively, but winning this suit isn't going to unparalyze her. What is she actually seeking as a result of this suit?
I don't think this story will result in my being more or less willing to stop and help someone in need, but then again I know just enough to know to do nothing more than needs to be done until better trained professionals arrive.
See bleeding? Apply pressure. Person not breathing? Give CPR. Broken bone? Stabilize it if necessary otherwise leave it alone. Beyond that the victim needs to hope true rescue folks are on their way.
