Probably what Telly Hudgins said to the cops, although much more 'slang' was probably used.
You only have to give a cop the cooperation he compels you to give, as in stay seated, keep your hands out of your pocket.
But I don’t have to answer a single question if he wants to be a jerk.
Cop, “what are you doing out at this time of night?” After he makes sure I know he is king of the world and his crap don’t stink.
Me. Silence or smart ass answer, like, “walking, can’t you tell” as I open the glovebox for registration.
I don’t have to explain my purposes to intentions to him.
