It will not do to note that 99 percent of the time the police mediate conflicts without killing people, any more than it will do for a restaurant to note that 99 percent of the time rats don’t run through the dining room. Nor will it do to point out that most black citizens are killed by other black citizens, not police officers, anymore than it will do to point out that most American citizens are killed by other American citizens, not terrorists. If officers cannot be expected to act any better than ordinary citizens, why call them in the first place? Why invest them with any more power?

Legitimacy is what is ultimately at stake here. When Cooksey says that her son’s father should not have called the police, when she says that they “are supposed to serve and protect us and yet they take the lives,” she is saying that police in Chicago are police in name only. This opinion is widely shared. Asked about the possibility of an investigation, Melvin Jones, the brother of Bettie Jones, could muster no confidence. “I already know how that will turn out,” he scoffed. “We all know how that will turn out.”
