SAN FRANCISCO — We have a choice to make.

We can look at both violence and racism as scourges that all of us must join together to fight. Or we can turn the issues of crime and policing into fodder for racial and political division.

In principle, it shouldn’t be hard to recognize two truths.

Too many young African-Americans have been killed in confrontations with police when lethal force should not have been used. We should mourn their deaths and demand justice. Black Lives Matter turned into a social movement because there is legitimate anger over the reality that — to be very personal about it — I do not have to worry about my son being shot by the police in the way an African-American parent does.

At the same time, too many of our police forces are killed while doing their jobs. According to the National Law Enforcement Officers Memorial Fund, 1,466 men and women in law enforcement died in the line of duty over the last decade. We should mourn their deaths, appreciate the dangers they face, and honor their courage.

Now I’ll admit: It’s easy for me to type these words on a computer screen. Circumstances are more complicated for those on either side of confrontations over the obligations of our police forces. Things get said (or, often, shouted) that call forth a reaction from the other side. A few demonstrators can scream vile slogans that can be used to taint a whole movement. Rage escalates.

Moreover, there are substantive disagreements over what needs to be done. Those trying to stop unjust police killings want to establish new rules and practices that many rank-and-file officers resist, arguing that the various measures could prevent them from doing their jobs. This resistance, in turn, only heightens mistrust of the police among their critics.

But politicians and, yes, even political commentators have an obligation: to try to make things better, not worse. There is always a choice between the politics of resentment and the politics of remedy. Resentment is easier.

And so it was this week that the murder of Texas sheriff’s deputy Darren Goforth inspired Sen. Ted Cruz to say on Monday: “Whether it’s in Ferguson or Baltimore, the response of senior officials of the president, of the attorney general, is to vilify law enforcement. That is fundamentally wrong, and it is endangering the safety and security of us all.” For good measure, the next day, Cruz condemned President Obama’s “silence” on Goforth’s murder.

The problem? For starters, Obama was not silent. He called the slain officer’s widow on Monday and issued a statement saying he had told Kathleen Goforth “that Michelle and I would keep her and her family in our prayers. I also promised that I would continue to highlight the uncommon bravery that police officers show in our communities every single day. They put their lives on the line for our safety.” Obama has made statements of this sort over and over. Vilification this is not.

Over at Fox News, the campaign against Black Lives Matter has become fierce. Bill O’Reilly called the organization a “hate group” and declared: “I’m going to put them out of business.”

Let’s take five steps back. The movement for police reform was not the invention of some leftist claque. It was a response to real and genuinely tragic events. Silencing protesters won’t make anything better.

And some potential solutions don’t even make the political agenda. The easy availability of guns on American streets is a threat to police officers and to African-Americans in our most violent neighborhoods. Why are those who seek reasonable gun regulations regularly blocked by interests far more powerful than those who demonstrate in our streets?

On April 5, 1968, the day after Martin Luther King Jr. was assassinated, Robert F. Kennedy — who himself would be fatally shot exactly two months later — said this to the Cleveland City Club:

Whenever any American’s life is taken by another American unnecessarily — whether it is done in the name of the law or in defiance of the law, by one man or by a gang, in cold blood or in passion, in an attack of violence or in response to violence — whenever we tear at the fabric of our lives which another man has painfully and clumsily woven for himself and his children, whenever we do this, then the whole nation is degraded.

How much more pain must we endure before we recognize that these words are still true?
