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.[38][39][40]

The "National Youth Gang Survey Analysis" (2011) state that of gang members, 46% are Hispanic/Latino, 35% are black, 11.5% are white, and 7% are other race/ethnicity.[41]
According to the FBI Uniform Crime Reports, in the year 2008 black youths, who make up 16% of the youth population, accounted for 52% of juvenile violent crime arrests, including 58.5% of youth arrests for homicide and 67% for robbery.

According to the National Crime Victimization Survey in 2002, the black arrest rate for robbery was 8.55 times higher than whites, and blacks were 16 times more likely to be incarcerated for robbery than non-Hispanic whites. Robberies with white victims and black offenders were more than 12 times more common than the reverse.[43][44]

Makes that 6% seem a little more profound.
BTW, these are crime rates, not incarceration rates
