Even then that’s not a great metric. It’s only a good for identifying bias if we assume all interactions are the same. One where you stop someone for carrying a gun down the street va a traffic stop are going to be very different regardless of race. African Americans tend to live in more dangerous areas, so you’d expect encounters to lead to more incidents from that alone.

Ironically, in a world where police are told to be more sensitive to race, and to stop minorities less often, you’d expect shootings per encounter to go up, since less encounters are for smaller infractions.
