Overturning this law should never have even been a consideration. In fact, it should have never even become a law. There should be absolutely no need for this kind of law in any society built on common sense and logic. No firearm manufacturer, in fact no manufacturer of any legal product should need protection from lawsuits involving the misuse or illegal use of any legal product. Faulty products, dangerous manufacturing practices are a whole other issue, but that's not what this law is involved with.
And any attorney who would bring this kind of frivolous suit against a reputable manufacturer should be dis-barred. And as much as that, any judge who would hear this kind of frivolous suit should likewise be barred from the bench.
I'm so damned tired of all this craziness, lack of common sense, cancel culture, political correctness, etc, etc, etc.
