YOU weren't racially profiled. Your friends were. You just happened to be the white person in the car with four undesirables. (Or possibly four carjackers/ kidnappers who were taking you to parts unknown.) Honestly, there was nothing you could have said or done. Had you said anything, then the cop would probably have felt it necessary to escalate the situation so that he did not appear to be belittled in the eyes of four black men. Believe me, we appreciate your awareness then and your awareness now. Just continue the work.
