Thanks. Looks like Wally world had a security company. They'renot talking about what duties the security company had in it's contract. The article mentions negligence, which only applies if they had something specific in their contract, or knew the carjacker was a bad guy. It could be the security co. was negligent and Wally World just paid off the family, because they were nice. In general, no company is liable for such things as car jackings in their parking lot.
