True, but who are the primary practitioners of that culture? It's called "profiling," and it works for a reason.
True, I am not arguing against profiling. I agree with what you are saying. I am just saying that the predominate reason profiling works comes from the cultural or sub-culture, not from the race, of the individual. While it may be true that 99% of the "black-urban-gangsta" cultural is practiced by blacks, being black does not automatically include you in the "black-urban-gangsta" sub-culture. It is an individual choice, not a genetic predisposition.
Profile the cultural or sub-culture, not just the race. If the profile happens to include the fact that 99% of the "black-urban-gangsta" sub-culture practitioners are black, so be it. Profiling should be based on the behavior and demographic composition (sex, age, race, etc.) of the group in question, not primarily on race. There a a whole lot of other things that factor in to an individual's behavior other than race.
I agree that it is a fine line, and a lot of people don't see it (or want to), but I think it is quite clear, if you think about it.
