My point is that it shows the homicide conviction rates for both black and white people are both roughly what you would expect, based on a) the homicide victimization rates and b) the percentage of crime that is intrarace. Setting aside the biases of the judicial system, if X number of black people were killed by homicide then you can get a pretty good guess of how many black people committed homicides. The fact that this expected number of black homicide victims lines up with the number of black people convicted is a good sign, at the very least, that black people are not being convicted for crimes committed by white people, and therefore the ratio of homicides per capita between black and white people is roughly accurate.
