You'd be surprised. While basic prejudice of course exists, much commonplace "profiling" is simply driven by statistical signals that happen to correlate with various sorts of bad behavior. Socially aware minorities who wish to actively mitigate this part of the problem (which is otherwise the hardest to address, for fairly obvious reasons) might want to start dressing up with suit and tie when out in public, and driving cars that are nicely-maintained but not too "blingy".
Of course, this goes to show the extent to which police profiling is in fact about broader notions of class and subculture, and not limited to race.
