District 21 of the Chicago Police Department is made up of two distinctly different groups. There are the uniformed cops who patrol the beat and go head to head with the city's street crimes.

COPS follows police officers, constables, and sheriff's deputies during patrols and various police activities by embedding camera crews with their units. The show's formula adheres to a classic cinéma vérité ethos. With no narration or scripted dialog, it depends entirely on the commentary of the officers and on the actions of the people with whom they come into contact.
