"According to the US Department of Justice, blacks accounted for 52.5% of homicide offenders from 1980 to 2008, with whites 45.3% and "Other" 2.2%. The offending rate for blacks was almost 8 times higher than whites, and the victim rate 6 times higher. Most homicides were intraracial, with 84% of white victims killed by whites, and 93% of black victims killed by blacks."
You think that 12 % of the population committing 52% of murders is the same rate as 63% of the population committing 45% of the murders. Interesting must be common core math you are using.
