Perhaps get someone's ire up just a bit regarding profiling. Be a policeman on the street attempting to be as efficient as possible. Whatever the culprit has done, an officer gets on the scene and gets a description. He puts on the air description of perp: B/M, 25-30, 6/2, 200, wearing blue t - shirt and white pants and black loafers. Officers on the look out eliminate a hell of a lot of people who do not fit the description. They are selective in the persons they stop and question.
Or, walk the line officer makes the scene and put description of perp on the air: Wearing blue shirt. Officers stop everything in the city who wears a blue shirt. Chances of success are slim, but have a very impressive trip sheet to show activity of a super cop doing extreme amount of work, just not productive.
Supremes probably should distinguish when profiling is appropriate to keep those who do not fit profile from being inconvenienced.
