Well, look who found google. So the fact that they had almost a thousand complaints over a 10 year period about other people being burned by the temperature of the coffee (including some third degree burns, which is what Liebeck suffered), and have literally IGNORED them, means nothing to you? Did you ever see the pictures of her burns?
A good analogy would be if the NFL were doing nothing about concussions now, not educating people, no rules changes, no requirements for players who have suffered a concussion. The NFL knew all about it and the risks, but just ignored it completely. You said yourself in this thread that there's no way the NFL could have known about the risks of concussions years ago. Sounds to me like that's your justification for saying this lawsuit would be frivolous. Leads me to believe that if the NFL did know the effects of concussions it would make a difference to you.
Well McDonald's knew.
And news flash. Coffee is made to have contact with your body. If she had tried to take a sip and the lid had popped off and coffee went all over her face and gave her third degree burns, would that make the lawsuit legitimate to you?
You know what, it doesn't matter. The real issue here is that the jury system is set up the way that it is in this country so people who feel like they have been wronged have a recourse against these multi-million dollar corporate behemoths who turn a blind eye to these issues. It's not your place or my place to judge whether that person's lawsuit is frivolous. It's the courts' and the juries' places to do that. People like you who think they are judge and jury without knowing all the facts have led to this "tort reform" business that everyone harps about. It's hurting real people with real issues. And it's not helping the corporations or medical practitioners with their insurance costs, which is typically the stated benefit of "tort reform."
