Whom are police officers turning their backs on when they refuse to face Mayor Bill de Blasio, and whom are they protecting? On the night of Saturday, December 20th, after a man named Ismaaiyl Brinsley shot the officers Wenjian Liu and Rafael Ramos, execution style, outside of a Bedford-Stuyvesant housing project, a line of officers who'd gathered at the Woodhull Medical Center faced away from the Mayor as he walked passed them. They were mourning and distraught; one might wish that they realized more fully that the city and its mayor were mourning with them, but it was the sort of act of shocked grief that can be forgiven the next day. That was more than a week ago, though. Since then, Patrick Lynch, the head of the Patrolmen’s Benevolent Association, a police union, all but called de Blasio the officers' killer—he had "blood on his hands." At Ramos's funeral, held two days after Christmas, the officers in an overflow crowd outside the church turned their backs on the screen showing de Blasio giving his eulogy. Then, on Monday, at the graduation ceremony for the city's police academy, members of the audience shouted "Traitor!" when de Blasio spoke, and there was scattered back-turning, though not, apparently, among the newest officers. De Blasio, in a speech that was almost abject, said, "You will confront all the problems that plague our society—problems that you didn't create." According to the Times, "a heckler yelled out 'You did!' and drew applause."

But what, exactly, did de Blasio do? What was his "betrayal," to borrow another of Lynch's bitter phrases? After a grand jury failed to indict anyone in the death of Eric Garner, even though a video showed an officer putting him in what, by the N.Y.P.D.'s own rules, was an impermissible chokehold, de Blasio said that many in the city "did not want" that outcome. But he was less than explicit about what he wished, other than for any protests to be peaceful and, more generally, to not have to worry about how the police might deal with a child like his son Dante. Perhaps a fantasy mayor would have come out smiling following the news of the grand jury and presented it as a vindication. But what or whom would have been defended with a gesture like that? How would the city have been served by what whole communities would have experienced as scorn? (The Mayor may be the target here, but the message that members of the police will turn their backs on those who criticize them, excluding them from a circle of protection, is broad and unhelpful.) De Blasio promised, in his campaign, to do away with the N.Y.P.D.'s stop-and-frisk policies. A court case had already given him and the city good reason. Voters agreed, a source of tense confrontations was removed, and, in the year since, crime has fallen. He reacted defensively to criticism of his wife’s chief of staff, who, among other problems, had a boyfriend with a criminal record. Yet, at the same time, he brought in Bill Bratton, hardly a flaming radical, as his police commissioner.

Creating a space for peaceful, lawful protests is not what killed Ramos and Liu. The murderer was Brinsley, a lifetime petty criminal who didn't even live in New York. Hours before the killings, he was in an apartment in Baltimore, pointing a gun at his girlfriend, Shaneka Thompson. He shot her in the abdomen; she survived, and he fled to Brooklyn. He posted an Instagram message saying "I'm putting wings on pigs today. They take 1 of ours ... let's take 2 of theirs." At that point, he had already come close to putting "wings on" Shaneka Thompson, and any police officer in the country would have had good reason to arrest him in defense of a young, black woman. Brinsley added a "shootthepolice" hashtag and ones about Garner and Michael Brown; after news of the shooting, those words, his would-be excuses, were seen as explosive. They only are, though, if someone like Brinsley gets to decide what is "ours" and what is "theirs"—and who the us in "let's" is. And he doesn't. Ramos and Liu were ours; claiming them has nothing to do with race. Brinsley was nobody's.

There is clearly anger toward de Blasio within the police force, as well as heartfelt dislike. It may be the legitimate result of a thousand acts of clumsiness and cultural blindness on the Mayor's part. No matter the statistics, officers like Ramos and Liu, or Russel Timoshenko and Herman Yan, put their lives on the line. De Blasio is the mayor, and it is his job to form connections with people who have one of the hardest, most dangerous jobs in the city. Clearly he can do better, but it is also clear that he is trying. The police may feel left out, or that people don't understand the hard work they have done—that new residents born in distant, safer places think they are the ones who've transformed Bushwick or Bed-Stuy, as if a peaceful city requires only artful curators, not custodians. For members of the police, suddenly places they didn’t want to patrol are places they can hardly afford to live on an officer's salary. Their dismay may be understandable. But it should not be enraging. New York is a much safer city than it used to be, and that requires an adjustment by police officers, too. This may be where the N.Y.P.D.'s own leadership has failed. The Patrolmen's Benevolent Association recently put a message on its Web site saying "Don't let them insult your sacrifice!" It linked to a (https://www.nycpba.org/miscellaneous/council-funeral.pdf) that officers could sign asking de Blasio and City Council Speaker Melissa Mark-Viverito not to come to their funerals if they are killed in the line of duty, saying that it would be an "insult" due to their "consistent refusal to show police officers the support and respect they deserve." The statement is not a request to remove politics from funerals, but rather an effort to politicize them.

De Blasio did go to Ramos's funeral—the insult would have been if he hadn't. He spoke about Ramos's love for his wife, Maritza ("the love of his life and the partner in all things"), and his sons, Justin and Jaden ("they are Mets fans. God bless them. And he loved playing basketball with his sons in Highland Park"). He added a few words in Spanish (“era un padre y esposo amoroso, un hombre de mucha fe”). Officer Ramos was studying to be a pastor, and Vice-President Joseph Biden, who also spoke at the funeral, said that he "didn't just have a Bible in his locker; he lived it in his heart." Wenjian Liu will be buried this coming weekend (the services were delayed to allow relatives to get here from China; that these two men are the ones Brinsley found randomly is a reflection of the N.Y.P.D.'s real diversity, as well as the city's). Many of the officers outside were not New Yorkers; they had come from California, the United Kingdom, and places in between, and so it is hard to say what they knew about de Blasio when they made their act of protest, or what they knew about this city. They might answer that they knew what they needed to about being cops, and, sometimes, about being alone. That would be better expressed by moving toward people—the officers' families, the communities they live in, even the Mayor—rather than showing their backs. The same could undoubtedly be said of some of those in the crowds that protested the grand jury's verdict. Facing each other, those on each side might be surprised by what they see. The time for turning away is over.
