If you want to fix something, the first thing you have to do is figure out what you are trying to fix. So if you are a GVP activist or supporter, obviously you want to do something about gun violence.  But how do you define ‘gun violence?’  Does it mean when someone uses a gun to hurt someone else?  Does it mean when someone uses a gun to hurt themselves?  How about when the gun was used intentionally?  Or unintentionally?

And even if you decide that ‘gun violence’ includes all those categories, the 110,000+ or so physical injuries that happen each year when the trigger of a gun is pulled may only be the tip of the iceberg.  And it’s a very large iceberg, believe me. To begin, we only count victims by the number of people who end up with a bullet in their bodies.  What about the people who witness the assault? Numerous studies support the idea that witnesses to shootings are often severely traumatized, particularly when these witnesses happen to be kids.  What about people who are threatened with a gun but luckily are able to walk away without getting shot?  This happens many more times each year than the few times that guns are used for self defense.

The problem in trying to figure out the real size of the iceberg is compounded because Gun Nation decided years ago that there’s no iceberg at all.  In fact, the truth is that guns have nothing to do with violence because it’s the people stupid, not the gun.  The gun-nut lobby is so committed to disconnecting the word ‘gun’ from the word ‘violence’ that many of them refer to guns as ‘tools,’ which has got to be about the stupidest, most pandering and meaningless description of any consumer product that has ever been produced anywhere, any time.

But let’s get back to the serious side of the issue which has been raised in an article just published by the Washington Post. The article describes a technology, ShotSpotter, which is now operating in more than 60 locations around the U.S., and basically is used by police departments to figure out how and when to deploy resources in response to spikes of violence measured by the number of guns that go off in the areas where the technology is deployed.

Guess what?  According to the data generated by ShotSpotter, gun violence went down from 2014 to 2015,  The ShotSpotter website contains a very interesting report which compares data from 2014 to 2015 in the 46 cities that deployed the technology both years. And with the exception of cities in the Midwest like Chicago and St. Louis, reports of gunfire are way down in the East and West, and even slightly lower in the South.

My only issue with the report’s methodology is that it generates gunshot rates by comparing the number of gunshots to the geographic area in which the technology is deployed, whereas gun injury rates developed both by the FBI and the CDC compare injury numbers to an area’s population. At this point that we can’t really tell whether the measurement of gun violence by ShotSpotter can really be compared to the usual way that we measure gun violence, namely, by the number of bodies that end up in ER, Trauma, or the morgue. On the other hand, we have to assume that outside of shooting ranges or hunting areas, anywhere that a gun goes off, gun injuries won’t be far behind.

I happen to think that ShotSpotter technology is an effective response to gun violence for the simple reason that the data collected by a ShotSpotter device, if nothing else, tells us where guns are can be found. And despite what Gun Nation would like to believe, it’s the gun, not the person, which causes 31,000+ gun deaths every year. How we find and (yes) grab those guns remains to be figured out.  But ShotSpotter is a good first step.
