Sorry Ard, while you are right that the young blacks have a bit more attention from the boys in blue, this is largely due to the existence in their culture of anti authoritarian habits. Ally this with a strange almost pathological requirement to be respected by others, and the fact that people have reportedly been killed in that community for 'dissing' [disrespecting], another member of that community.
A macho, anti authoritarian society is always going to attract the attention of the forces of law and order.
