Can't speak for anyone else but I certainly wasn't insinuating anyone can sue anyone. However you keep stating this fact about discharging energy. While it may be taught in 8th grade science, practically speaking, that doesn't mean people really believe there is any danger using as common an item as a battery. Again, basic statistics tells us all its NOT dangerous.
Educate people to be safe. If they aren't it's on them. But I can't say the all factions of the vape community are doing a great job educating... Not when I can buy a mechanical online and get the product and batteries in my hand and never see a warning at all.
Why do we need so many warning labels? I do see your point but then if you are the one to get hurt is it not your responsibility to your self to know how to use anything safely.
I think we need to teach people to do risk assessment before they do any task then we don't need warning labels.
Ignorance of the law is no excuse so shouldn't ignorance of using something safely, be it batteries a ladder exct.....
