Mr. McKenstry has, if not defenders, then at least people who see his side of the story. Given the history of discriminatory enforcement by Baltimore police, Mr. McKenstry could well have come into the traffic stop with the assumption that he would have been left alone if he had been white. Even so, what did he accomplish by refusing to hand over his license and registration? What did he accomplish by refusing to sign the tickets Sergeant McGowan eventually gave him? What did he accomplish by putting his hands on the roof of his car and demanding to be arrested? Even if this was arbitrary enforcement — and to be clear, we don't know enough about what led up to the confrontation to make any judgments about that — Mr. McKenstry, of all people in this city, had more productive avenues open to him to raise the issue.
