how does that even remotely answer my question?
You are asking for examples of black on white violent crime. Using a very specific incidence to make your point harder to counter isn't going to change the fact that you're wrong.
Have you heard of De'Marquise Elkins? He shot and killed an innocent Caucasian baby in front of his mother at gunpoint.
Have you heard of Dillon Taylor? He was an innocent white teenager who was shot and killed by a police officer of color.
Was your answer no? Even if it was yes, the sad, vast majority of people would say no. Yet, almost all of them could tell you exactly who Treyvon Martin and Michael Brown are. There is no doubt that the media exploits racial tension against whites by blacks for ratings. Seriously, it's like not even debatable. Even if white on black vs black on white crime was even (which it is not) you would STILL see significantly more attention delivered to white on black violence because it's easier to spark outrage.
