From 1949 to 1957, Dragnet pioneered new levels of realism on radio. Every crime investigated by Sergeant Joe Friday was taken from the actual case files of the Los Angeles Police Department, with only "the names changed to protect the innocent". There were multi-layered sound effects; the actors used accurate police lingo, abbreviations, and penal codes; and the show didn't shy away from stories about heinous crimes or stories that had unhappy endings. Created and produced by Jack Webb, Dragnet was much more than "just the facts".
Any additional comments?
A note comes in to the narcotics group within LAPD, having originally been written to Juvenile. The note sets up a meeting with officers to disclose information on who is in a local drug ring. Friday and Smith conquer another drug issue.
