It is hard to think of any rational to stop a well-dressed person engaging in no shady behavior and immediately escalate to “lie face-down with your hands over your head.”
There are other news reports of similar incidents with black men. If race is not a factor, we would expect to see many more white than black men wrongly treated in this way, as they are a larger share of the population. I’m not aware of similar reports for white men, but would be interested to see them.
Re traffic stops: The idea that you can’t see the race of a driver while driving behind them is ludicrous. Next time you’re on the highway look in the rear view mirror of the car in front of you. You can see the person’s face.
If they’re actually stopping and searching people on some heuristic that just happens to be correlated with race, they should stop - it’s a bad heuristic. They’re searching black drivers at double the rate of whites, but finding contraband at a lower rate.
Clearly something they’re doing is broken, and it manifests as an undo burden on black drivers.
