This category brings together articles about law enforcement bodies, regulatory agencies, private security companies, as well as high-profile criminal cases and human rights activity in Nizhny Novgorod and the surrounding region. It presents both historical material — from the pre-revolutionary gorodovoy (city constable) to the Soviet-era militsiya — and present-day structures: the Volga-Oka Directorate of Rostechnadzor, Private Security Companies in Nizhny Novgorod, and specialized training institutions. A separate layer of material covers specific criminal cases, court proceedings, and violations of the law that drew public attention in the region.
