For some reason my entire post didn't take, so I'll write that last portion again-

Given the reality of race in the USA, I wonder if the results would have been the same if the lone person walking had been a Black man in a White neighboorhood-particularly in if the White neighborhood is middle class or upper middle class, and regardless of whether the Black man had ID or was civil to the police officer.

Indeed, Black men have been killed for happening to wander into White middle class neighborhoods, and vice versa I'm sure.

There was one case of two Black men who were killed in New York City some years ago when they walked through a White neighborhood because their car had broken down. I don't remember the names, but I recall that a group of men chased them to a highway, and I believe that is how at least one of the men died, though my recollection is that two men died.
