In the case of race you can't just ignore that black people do roughly 50% of violent crimes (just look at arson, don't even try to excuse it) and make up 25% of the lethal shootings with police.
It's also obvious why the racism is the other way around than some people make it out to be. Every police officer thinks twice to shoot on someone with dark skin because of the media coverage that can and often does take place. With killing white people, even if unjust this is rarely if ever a headline (except you can spin it, like when he helped a PoC).
