No, it probably wouldn't. One, he didn't get "attention". He got suspicion and aggressive questioning. Two, in the US there is easily demonstrable bias against black people. If you are interested, I recommend going to Harvard's Project Implicit, taking some of their tests, and reading the research results. And the bias extends well beyond the visual; it's enough to have a black name, as is shown by the classic paper: "Are Emily and Greg More Employable than Lakisha and Jamal? A Field Experiment on Labor Market Discrimination" https://www.nber.org/papers/w9873
