Perhaps we could start by actually researching the problem. Gaining knowledge is usually a pretty good place to start before making any changes. After all, if 58 people at the concert died and another 500 were sickened, all by food poisoning we'd be looking for the cause to prevent it from happening again. Or if it'd been a massive fire at the Mandalay Bay that killed 58 and injured hundreds we'd be looking at what went wrong with our fire safety rules. But the main governmental research organization with the goal of keeping people healthy doesn't do that when it comes to guns killing people.

The consequence is that we’re flying blind on gun violence. Rosenberg and other experts list four topics on which research is crucial. First is the scale of the problem — how many people are shot, is the number rising or falling, who gets shot, under what circumstances, and with what weapons? Second, what are the causes? “What leads people to shoot other people or kill themselves?” Rosenberg asked. (Two-thirds of gun deaths are suicides, he said.)
Third is learning what works to prevent gun violence, and fourth is figuring out how to translate these findings into policy. Legislators across the country have enacted laws allowing open-carry of firearms on the street or in public places, or authorizing teachers to carry arms in the classroom or on campus, “with no idea whether that would result in more people being killed or more lives being saved,” Rosenberg said.
