Night Watch was a radio version of COPS except you don’t see the cops in action but you do hear everything that happens when a criminal is being questioned by the cops.
These are true stories recorded as they happen by a police reporter who rides in the patrol car with the officers. This to me is the most realistic old time radio program since there are no actors and what you hear are the actual words of the cops, criminals, witnesses and parents when juveniles are involved.
One of the stories is about a mother that leaves her two kids in the car on a cold night so she can go in a bar. The police are alerted and check on the kids and question the mother.
Another story is about a man stealing bedding from a nearby motel to take back to his trailer.
This show is not mentioned much in old time radio circles but if there was ever a reality radio show Night Watch would be the one most remembered.
This is a very good description of the shows:
