Here’s a good article detailing the stats from a few angles. It concludes:
The truth is that the raw statistics can’t tell us whether the police are treating African Americans differently from white people. To understand that, we’d need to look at more details about what happened in each incident. There’s a big difference between a case where someone was shooting at the police, and a case where someone was passive and unarmed.
One person who has tried to do that is an economist from Harvard University called Roland Fryer, the first ever African American to win the prestigious John Bates Clark medal in economics. This month Fryer released a preliminary study examining records from 10 cities and counties, with the best data coming from Houston – it’s not yet peer-reviewed, but it has received a lot of attention in the press.
Fryer’s research suggests that African Americans and Hispanics are substantially more likely to experience force in their interactions with the police – such as having a gun pointed at them, being handcuffed without arrest, or being pepper-sprayed or hit with a baton. This racial difference is reduced, but doesn’t completely disappear, when Fryer adds all sorts of statistical controls such as whether the incident was indoors or outdoors, in a high-crime area, took place at night, and so on.
However, Fryer doesn’t find any racial difference in the cases where police offers actually shoot someone.
