This is the thing, black on white crime is not covered 24/7, and by every news station because white people don't have leaders, like the black community (Sharpton, Jackson, etc). Although, Sharpton and Jackson are not leaders, just greedy assholes. But much of the media coverage happens when Sharpton and Jackson rear their ugly head, and protests happen.
When white crime happens, there are no white leaders protesting, and white people tend not to rally about this stuff. So, what is too cover, except the actual crime itself. The news will basically say a crime occurred, then it goes away. For the media, there is no sensationalism behind just a crime occurring. What they are looking for is protests and leaders, like what occurs when a white cop shoots a black person.
I obviously think all crime should be given equal attention, but in the media's eyes, they are looking for the protests, rallys, and the "leaders" protesting. White community doesn't have this, so the media just reports on the crime, and its never mentioned again.
