ACME Bowling Lanes contracted to have AVM Security Company provide an armed security professional at ACME's facilities every Friday and Saturday night. One Friday, Paul was assaulted and seriously injured by an unknown person in ACME's parking lot. Paul brought an action against AVM. Paul maintained that AVM had breached its duty to protect him. AVM denied this allegation. Explain the relevant law (from Chapter 16) and what Paul will have to prove to win his case against AVM?
