Can a police officer be held liable in damages for failing to come to the aid of another person?

"[P]olice officers and other public security officers, like other persons, generally may not be held liable in damages for failing to take affirmative steps to come to the aid of, or prevent an injury to, another person. 'As a rule, one has no duty to come to the aid of another. A person who has not created a peril is not liable in tort merely for failure to take affirmative action to assist or protect another unless there is some relationship between them which gives rise to a duty to act.' " (Zelig v. County of Los Angeles (2002) 27 Cal.4th 1112, 1128-1129.)
