California transit cop verdict sparks looting
The word “cop” is a slang term. When used to refer to police, it is a pejorative. The use of the word “cop” by news media reflects laziness, unprofessionalism and disrespect.
I would describe that word as informal, the same thing my dictionary calls it.
As far as I can tell it was not used in our actual stories. However, it is a very convenient word to use in headlines, where it takes up a lot less space than officer or policeman: GBU Editor
