Narc is also the term used for an informant. If someone gets caught with drugs, they may turn in the person they bought the drugs from to lighten their prison sentence. Sometimes the police (or DEA, or whatever) will keep the person around for a while to bust other individuals.
It's easier to scare someone already in "the scene" into becoming an informant than it is to place a police officer in "the scene."
