The escalation in Mr. McNulty’s situation confirms Tom’s prediction that the police are not able to protect her. Furthermore, the vague nature of her husband’s threat suggests that he understands the limitations of the police and is using them to his advantage; thus, although Ms. McNulty accurately interprets the blank letter as a threat, the police legally cannot do so. Thus, Tom once again functions as an alternative form of protection for Ms. McNulty where legal institutions have failed.
