Oh, blacks clearly murder one another at a far higher rate than whites murder one another. But the stubborn fact remains that cross-racial murder is relatively rare, in both directions.
And of the cross-racial murders, the blacks are more murderous against whites, than whites are against blacks. This is true in raw numbers, and in percentages. The blacks, 13% of the population, murder more whites, than whites murder blacks.
If one focuses on the interracial murders only, what we have is more a problem of black against white. An objective population would notice this. So would an objective commentator.
