In the U.S., slang for the police (colletively) is "the cops," and for a police officer, "a cop." In the past, they were called "the fuzz" or even "the pigs," though those terms have gone out of style. In the WordReference dictionary and past forums, I don't see a discussion of Italian slang terms for the police, or a police officer. I'm writing a crime novel set in Rome, set in the current day, and the teppisti would sound more authentic if they used the right slang word, instead of polizia, poliziotto, and poliziotta (a woman officer). Any help you can give would be appreciated.
