What a Claim Against the Property Has to Show: Duty, Breach, Causation, and Damages
Each element has to be shown, and each is argued on its own facts.
Duty is the starting point: whether the person or business that controlled the property owed the injured person reasonable care against this kind of attack, which usually brings foreseeability back into view. Breach asks whether the security in place fell below what reasonable care required in that setting. Disputes often center on what measures existed and whether they were adequate.
Causation is often the hardest element. The person who fired the gun made a choice, and that intervening criminal act raises the question of whether the property's security failure was a legal cause of the harm at all. Courts examine whether the attack was a foreseeable result of the security failure and whether reasonable measures would likely have made a difference. A shooting alone does not prove that a property was at fault.
Damages are the losses that follow. The categories the law may allow can include medical expenses, lost income, and pain and suffering. When a shooting is fatal, a family may have a wrongful death claim. Wrongful death is a claim brought after a death caused by another's wrongful act or neglect, by the family members or estate a state's law allows, for losses the death caused them. Which categories are available, and to whom, varies. Our page on who can bring a claim explains this in more depth.
Your own conduct at the time can also come into the picture. Under a comparative fault rule, any share of fault assigned to you can reduce what is recovered, and in some states it can bar recovery. Under a stricter contributory fault rule, any fault at all can bar recovery. States differ on which rule applies and how, which is one reason the state where the shooting happened carries real weight.
For an injured person or family, the practical consequence is that a strong showing on one element does not make up for a gap in another. It may help to think through each in turn: what made the attack foreseeable, what security was missing, how a different measure might have changed things, and what losses followed. Those are the questions a conversation with an attorney usually works through.
