Peace to you too.  I'll be done in a second.  I associate racial profiling with traffic stops because that's where racial profiling typically occurs, and there, it's illegal.  Cops simply can't stop someone without at least reasonable suspicion, and we agree, they can't have reasonable suspicion that someone's in the country illegally based solely on how the person looks or speaks.  

But you extend the concept to apply to situations where the cop's questioning of the subject is legal.  You would have it that the cop can ask the subject this that and the other, as the law already provides, but not about his status.  I asked you why, if the cop can ask about this, that, and the other, the cop can;t also ask about status.  You didn't answer that fair, legitimate question.  Having no answer, you nevertheless insist you are right and shut off discussion.  OK.  Peace.
