Where does the term 5-0 or Five-O for police officers come from?
That's interesting. Are there any other explanations for the origin of this term?
Another theory suggests that the term was used by police themselves in reference to a particular radio code that was associated with a police officer needing assistance or backup. The radio code was 10-50, which may have eventually been shortened to just 5-0, leading to the term being used as slang for police officers.
