It has been a year since my assistant, Jennifer Mascia, and I started publishing The Gun Report, an effort to use my blog to aggregate daily gun violence in America. Our methodology is pretty simple: We do a Google News search each weekday morning for the previous day’s shootings and then list them. Most days, we have been finding between 20 and 30 shootings; on Mondays, when we also add the weekend’s violence, the number is usually well over 100.

From the start, we knew we were missing a lot more incidents than we found. The Centers for Disease Control and Prevention, after all, says that nearly 32,000 people are killed by guns each year. Slate, the online magazine, which tried to tally every gun death in the year after the tragedy in Newtown, Conn., arrived at a number of 12,042, far higher than ours. (We include gun injuries as well as gun deaths.)

Part of the issue, as Slate has noted, is that it is impossible to track suicides using news media accounts — and suicides, according to the C.D.C., account for some 60 percent of gun deaths. But it was also obvious that a Google News search was bound to miss plenty of examples; that’s just the nature of the beast. Comprehensiveness was never really the point, though. Mostly we were trying to get a feel for the scale and scope of gun violence in America. A year later, it seems like a good time to take stock.

First, the biggest surprise, especially early on, was how frequently either a child accidentally shot another child — using a loaded gun that happened to be lying around — or an adult accidentally shot a child while handling a loaded gun. I have written about this before, mainly because these incidents seem so preventable. Gun owners simply need to keep their guns locked away. Indeed, one pro-gun reader, Malcolm Smith, told me that after reading “about the death toll, especially to children” in The Gun Report, he had come to believe that some gun regulation was necessary. He now thinks gun owners should be licensed and “should have to learn how to store guns safely.” No doubt he’ll be drummed out of the National Rifle Association for expressing such thoughts.
