McDonald’s case

After a little more research about the McDonald’s case, it’s known that the plaintiff’s attorneys discovered McDonald’s documents showing that more than 700 people had complained of being burned by its coffee from 1982-1992. Some claims involved 3rd-degree burns like this customer. McDonald’s admitted that they kept their coffee at 180-190 degrees Fahrenheit. (Coffee served at home is 135 degrees, and other restaurants keep coffee at much lower temperatures than McDonald’s). 
Do you believe that this is demonstrating that the company was aware of the nature and extent of this hazard …? with cited and references.
