Re: "what kind of person walks in to a store,steal something, get caught. and then threatens the owner and walks out with the merchandise, does anyone teaches values anymore."
Yes Brown acted in a reprehensible way in what he did. Still, plenty of White teenage boys do similar things in White middle and upper middle class neighborhoods and if they do get caught and it gets them in trouble their parents use connections or money to get them off the hook. Middle class young Whites are also currently the main users of heroin and prescription narcotics but they also get arrested and locked up for that much, much less often than minority users.
And these White kids don't get shot or even hassled very much for walking in the middle of the street.
