The people in charge deliberately obscure that particular stat. I would guess (with no hard facts at hand) that the numbers of blacks murdered by non-Hispanic i.e. non-Mexican whites is a very low number. Probably not more than one or two percent of the total numbers of blacks murdered.
Because every time a white person murders a black, it's headline news for a month. Not so the other way.
As in have you seen anything on the alphabet news about the six year old white kid in Kentucky murdered by a black man who broke into the kid's house and stabbed him to death? That happened a few weeks ago.
If it had been a white man who murdered a black kid like, we'd have wall to wall coverage and Obama lamenting all the "racism" harming black children.
If you only watched the media, you would think 91% of blacks are killed by whites. Blacks are always the victim. That’s the democrat/liberal media narrative.
