21ST PRECINCT was one of the realistic police drama series of the early- to mid-1950's that were aired in the wake of DRAGNET. In 1953 CBS decided to use New York City as the backdrop for their own half-hour police series and focus on the day-to-day operation of a single police precinct. Actual cases were used as the basis for stories. The Precinct Captain acted as the narrator for the series. The official title of the series according to the series scripts and the CBS series promotional materials was 21ST PRECINCT and not TWENTY-FIRST PRECINCT or TWENTY FIRST PRECINCT which appears in many Old-Time Radio books. It was mentioned in each episode's closing by the announcer  that, "Twenty-firstPrecinct is presented with the official cooperation of the Patrolmen's Benevolent Association an organization of more than 20,000 members of the Police Department, City of New York." Everett Sloane, Lawson Zerbe, Raymond Edward Johnson, Ken Lynch, Robert Readick, Gaylord Avery (announcer). 1/2 hour.   Less
