Not in any liberal news media.  But I have personally had it happen.  

I was in a Facebook conversation about the Eric Garner incident.  A black man accused me of being a "racist cop that just wants to kill people" based on knowing nothing more about me than I was a cop with a white picture in my profile.

The fact that I was the personal bodyguard to my black pastor at my predominately black church, and that I teach the Concealed Carry Permit course in Colorado to civilians did not matter - because he purely judged me on being a cop, and being white.

Sounds like black racism against white police to me.

If that had been the only incident where I have experience such treatment, it might be considered a fluke.  But it isn't.

In fact, the whole "Police target black men more than white men" assertion is predominately black racism against white police.  They don't care about the statistics showing black criminal activity at a "disproportionate rate", only that blacks get shot.
