I refuse to accept the view that mankind is so tragically bound to the starless midnight of racism and war that the bright daybreak of peace and brotherhood can never become a reality. - MLK
Going back to your OP that started all this, I understand the desire to have people of a similar background involved when going into a situation to relate to it. But I would argue that in the long term, it isn't going to make anything better, and maybe make things worse. The police deal is one of the last real vestiges of... supposed/inferred/implied (can't think of the right word, hope that gets across what I'm saying) racism? Is it better to risk someone's safety and wait for the black guy on duty to go to the area, or let the closest available get to the scene to deal with the situation? At some point, we need to move on from this idea that only the black cop will care about black people and stop assuming that whites don't care.
