when black people complain about white racism and black people dying at the hands of white people its the 1st and 2nd values on the FBI chart there comparing and saying. we do not kill you nearly as much as you kill us. we could change things but instead we would rather point this out or call you racist since you clearly do not value our kindness towards you. considering slavery and the Jim Crow/ Civil Rights era.
When white people reference white people killing blacks they compare the 1st and the 4th values on the FBI chart usually saying hey we don't nearly kill you as much as you kill your own, if you had more respect for each other and our system we would have more respect for you.
Blacks are from a more agrarian communal culture where we have different more moral based laws at least sentimentally and where those cross over with the morals of other races that's where the problems tend to pronounce them selves most often. the blacks that have no respect for any system are the ones who end up dead in most cases, and that's usually ok for the most part. its the Eric Garner type cases that get people riled up.
