The Chairman of the Black Police Officer’s Association expressed the solution to the problem very well this morning on NPR.
To paraphrase: Comply and then Complain, not the other way around.
The police are trained to get control of any confrontational situation, and they are trained that way for very good reasons.
These confrontations have little or nothing to do with the color of our skins. Rarely a racist officer may contradict the preceding rule of thumb, but the basic response to a confrontation remains the same. Do not argue and do not resist. Gather the names of witnesses and the badge number of the officer. Prepare to complain, but comply first. And it would be in your interest to remain polite about it.
Over the years I tried to tell my high school students exactly that (“Yes sir, yes sir…”) and how not to alarm the police. Some bragged how they would tell the cop to copulate with himself.
