Almost any other person would have been taken away in handcuffs, after attacking a hotel guest. There's the negligence.
Mrs. Harris did not want to leave the hotel. The employees had to physically subdue her and then she was led outside, and directly placed behind the wheel.
This aspect was soft-pedalled in the trail. Why, I'm not sure. But I can see why the daughter claimed negligence against the Hilton Hotel in her father's death.
I don't think this was a good example to support the author's premise. That's all that I am saying.
