According to laws in every state in the U.S., Walmart has a duty to protect its customers from violent crime while they’re on store property. Under an area of the law known as premise liability, victims and their lawyers have argued in hundreds of lawsuits that Walmart failed to provide enough security. To prevail, plaintiffs must prove that a violent crime was reasonably foreseeable based on a history of violent crimes at a particular Walmart. “They’re not easy cases,” says Memphis attorney Bruce Kramer, who has sued Walmart multiple times on behalf of clients who were the victims of violent crimes occurring on company property. “Proving what the duty is and the foreseeability issue is always difficult. You have a certain mindset of jurors who say, ‘Why are you holding the business responsible for the acts of this criminal?’ ”
