The mission of the UN police is to enhance international peace and security by supporting Member States in conflict, post-conflict and other crisis situations to realize effective, efficient, representative, responsive and accountable police services that serve and protect the population. To that end, United Nations police build and support, or, where mandated, act as a substitute or partial substitute for, host-State police capacity to prevent and detect crime, protect life and property and maintain public order and safety in adherence to the rule of law and international human rights law (S/2016/952).
