In 2005 (the last year I have information for), the homicide offending rate for whites was 3.5 per 100,000 population. For blacks, it was 26.5 per 100,000 population.
In 2005, 42.2% of all homicides in the United States were black on black. 8.8% were black on white. 3.2% were white on black. So in 2005, half of all homicides in the United States were committed by blacks. This despite the fact that blacks were only 12% of the US population.

Among both blacks and whites, young males are very disproportionately homicide offenders. In 2005, among whites, males 18-24 had a homicide offending rate of 22.4 per 100,000 population. Among young blacks, males 18-24 had an appalling homicide rate of 203.3 per 100,000.

Young black males 18-24 were 1.2% of the total US population, but were responsible for 27.8% of the country's homicides.

Since whites tend to kill whites and blacks tend to kill blacks, attempts by the police to catch killers and bring them to justice will not only net black homicide offenders disproportionately, it will also protect the rest of the black population who are disproportionately victimized by these people. Attempts by social justice warriors to prevent the police from pursuing black offenders will only result in more black victims. Among young black males, by far the leading cause of death is other young black males (not evil white police).
If black lives truly do matter, then this needs to be addressed and not swept under the rug for fear of being called "racist". In my opinion, the proximate cause isn't the police, but rather the breakdown and collapse of the black family, along with a hugely disfunctional youth subculture that absolutely glorifies violence. Raised in single parent homes with no male role models, too many young black males essentially raise themselves in sort of a
Lord of the Flies environment.
