I know about the rate that black people are shot by police (roughly 1/3 of victims, despite being less that 1/6 of the population), but what I wasn’t able to find was the rate at which black people are shot by black officers. Is this published?
I only found one site that seemed to have credible figures. They say that about ten percent of the police officers involved in fatal shootings are black.
The percentage of police officers who are black is around twelve percent so it appears that black officers involved in shootings are proportionate to their overall numbers.
From Little Nemo’s cite:"
Black officers account for a little more than 10 percent of all fatal police shootings. Of those they kill, though, 78 percent were black.
White officers, given their great numbers in so many of the country’s police departments, are well represented in all categories of police killings. White officers killed 91 percent of the whites who died at the hands of police. And they were responsible for 68 percent of the people of color killed. Those people of color represented 46 percent of all those killed by white officers."
I think they are comparing shootings to global arrest figures, not just to people who have been shot.
Basically, they are comparing the incidence of shooting to the incidence of arrest. More “contacts” makes for more opportunities for bad outcomes.
This suggests that the disparity is not in lethal violence during a policing event, but in the number of events. So the core issue is whatever causes more arrests and other police contacts; which could be due to race (racial profiling), poverty which is associated with race, or violent crime which is associated with poverty which is associated with race.
(Also, an earlier linked article did note a racial disparity in the amount of non-lethal force used by police when compared to arrests.)
