Almost no proposed restriction would make it meaningfully harder for people with guns on hand to use them. I couldn’t even answer my most desperate question: If I had a friend who had guns in his home and a history of suicide attempts, was there anything I could do that would help?

However, the next-largest set of gun deaths — 1 in 5 — were young men aged 15 to 34, killed in homicides. These men were most likely to die at the hands of other young men, often related to gang loyalties or other street violence. And the last notable group of similar deaths was the 1,700 women murdered per year, usually as the result of domestic violence. Far more people were killed in these ways than in mass-shooting incidents, but few of the popularly floated policies were tailored to serve them.

By the time we published our project, I didn’t believe in many of the interventions I’d heard politicians tout. I was still anti-gun, at least from the point of view of most gun owners, and I don’t want a gun in my home, as I think the risk outweighs the benefits. But I can’t endorse policies whose only selling point is that gun owners hate them. Policies that often seem as if they were drafted by people who have encountered guns only as a figure in a briefing book or an image on the news.

Instead, I found the most hope in more narrowly tailored interventions. Potential suicide victims, women menaced by their abusive partners and kids swept up in street vendettas are all in danger from guns, but they each require different protections.

Older men, who make up the largest share of gun suicides, need better access to people who could care for them and get them help. Women endangered by specific men need to be prioritized by police, who can enforce restraining orders prohibiting these men from buying and owning guns. Younger men at risk of violence need to be identified before they take a life or lose theirs and to be connected to mentors who can help them de-escalate conflicts.

Even the most data-driven practices, such as New Orleans’ plan to identify gang members for intervention based on previous arrests and weapons seizures, wind up more personal than most policies floated. The young men at risk can be identified by an algorithm, but they have to be disarmed one by one, personally — not en masse as though they were all interchangeable. A reduction in gun deaths is most likely to come from finding smaller chances for victories and expanding those solutions as much as possible. We save lives by focusing on a range of tactics to protect the different kinds of potential victims and reforming potential killers, not from sweeping bans focused on the guns themselves.
