Black on black crime has been a problem for many years which is why some of the links I sent were from different time periods. Just because they don't have a rally every few weeks doesn't mean it isn't a concern. The fact you don't hear much about it isn't because the black community doesn't care, it's because the media doesn't particularly care. The media is mostly concerned with breaking news and the right now, they don't give much coverage to persistent issues because people get tired of hearing about the same issues over and over.
