Whenever there's a national story about police, I always look for "Jack Dunphy's" reaction. He's an L.A. cop who wrote for National Review and I found this on Pajamas Media.
He closes with a story about being accused of using the "N-word" on the street. Fortunately for him, he had a tape recorder going.
It revealed, among other inconsistencies in my accuser’s tale, that it was he and not we who had so liberally used the accursed word, and that he used it, in the span of about 45 seconds, as a noun, a verb, an adjective, an adverb, and as something of an all-purpose interjection, a linguistic feat I suspect I may never see equaled.
