I agree with your assessment.
The questions remaining are:
1. Did the scooter woman and her husband perceive Crawford to be threatening because of the color of his skin? Would they have been as alarmed if it had been some blonde kid dressed in jeans and a t shirt?
2. Did the police react, in part, because of the color of Crawford's skin? Would they have immediately seen any person of any color holding a bb gun as a threat? Even that blonde kid?
I agree with the original assessment.
Your questions are racist questions. The color of his skin is what it is. The color of my skin is what it is. We are not color blind. But any given person, I hope you agree, should be judged as a package. Not by the color of his skin alone. Not by the length of his hair alone. Not by what he wears alone. Not by what he says and does alone. Not by who he is with alone. Not prejudged by any of these alone.
I do not know the races of the scooter woman and her husband. I do not know the race of the policeman. I don't know if Crawford was as black as my freshman roommate from Nigeria or as light as Derek Jeter, or was from Jamaica.
Race is a component of judging other people. A psychological truth is that we like people who are like us. We distrust people who are not like us instinctively.
People who are religious like people of their religion. People who are atheist like other atheists. People who dress well like others who dress well.
Don't ignore race, of course, but don't dwell on it. Don't stretch those racist pants to fit.
