I think the decision in this case is partly a result of the way the American legal system works. If you are a victim of an accident/disease the only way you can get financial help is to show it is someone’s fault. In countries with public healthcare and some kind of automatic compensation for accidents there isn’t such a great need to sue someone.

I agree that it needs to make be made very clear by what percentage something raises the risk of cancer. ‘Hot drinks may raise the risk of cancer by .001%’ doesn’t make such a good headline.
