The Narrative

The news media employs the concept of a "narrative" in order to report all instances of dog-bites-man and avoid reporting on all instances of "man-bites-dog".

So if you have a black man badly beaten because of his race outside of a boisterous town hall meeting in 2009, it doesn't get reported because he was beaten up by leftists. There are a near-endless number of instances of selective reporting. All you have to do is look for them.
