Businesses still must have liability.I understand both sides of this and empathize with each.
For some reason however, I am liable and carry insurance on home policy for people who are injured while on my property. Kinda like the scenario if one has a pool and a kid jumps the fence and drowns, the home owner is responsible.
I have a hard time with duality in our legal system. It's the same way with Obama care and some certain people exempting themselves from the requirements.
Don't make laws that apply to me but not to thee.
Is the question meant for businesses only, or does it apply to all establishments, such as state, and federal buildings? Say you're required to be in a courthouse, under penalty of law. And there's a shooting. You weren't there by choice, and you got injured.
Businesses still must have liability.
If you tell someone they cannot carry in your home and they are killed during a home invasion, you are not liable for their injury solely because you do not allow guns in your home.
If they trip and fall on the sidewalk your liabilty would cover it as would a business's.
If you have a CCW and someone in the public sees your weapon while you are carrying, you have committed a serious offense and could lose your CCW license for it, if they mentioned it to the Sheriff.
Keep it concealed = no problem.

Back to the original question.....
Imagine that you are carrying concealed, & you go to a store and while you are shopping an armed robbery begins.
You toss a can of beans 3 rows down the way, and while the robber is distracted by all the noise of shit falling off the shelves you sneak up behind him, stick your pistol in his ear and take his gun away from him.
His partner who was already in the store before the robbery began pulls out his gun and shoots you. You end up in the hospital with half a liver missing. Both of the robbers are captured.
The store had a sign on the front prohibiting the carrying of firearms.
Does the store sue you? Do you sue them? Are you prosecuted under the law? Can you sue the store because "...it never would have been robbed except for that stupid rule which emboldens the criminals"? ( maybe in California...)
Real life is often complicated like that and there are no easy answers.
I am no lawyer, however I believe that there is one generally accepted answer in court and that is: "I did what a prudent man would do, under a situation, which is not covered exactly in the law."
If, in fact, that is what you did.
It's also illegal to carry in the USPS parking lot and building. The USPS and Court are the only places I don't carry. If I go to a business that prohibits carry then I'll wear an extra layer of clothing to conceal rather than just my t-shirt. I'd rather a misdemeanor charge than be caught unarmed in a life-and-death situation.
