In an inadequate or negligent security case in New Jersey, what needs to be proved is that the defendant deviated from what should have been done to prevent foreseeable harm or a foreseeable crime. The plaintiff must prove that the defendant did not take proper steps in preventing that foreseeable harm. The burden of proof is on the plaintiff to prove that the defendant was at fault, and the plaintiff must prove this by a preponderance of the evidence, which means attorneys have the burden of proving that it was more likely than not that this defendant acted negligently.
