I personally think that we, as a society, have gone overboard with warning labels. Example? I bought a gallon of milk the other day. Printed on the label was the following text: "Allergy Warning: This product contains milk". I bought a jar of peanuts, that carried this little gem on it's label: "This product was processed on machinery that processes nuts, in a facility where nuts are stored"
In both cases, my thought was "Well, duh, of course". I hope that anyone with a dairy allergy or a peanut allergy wouldn't need the warning on the label to tell them to stay away from those products. But, obviously, the warning labels are there, which means someone had to have sued the company over the lack of a label.
We do not need more warning labels. We need tort reform, and we need judges that aren't afraid to throw these cases out. More warning labels aren't going to do anything, society is already oversaturated with them, and the labels have reached the point where they're just being ignored.
