KQED: There's this very common belief that people are safer if they own a gun or if they have a gun in their home, and you dug into the evidence. Tell us what did you find?
Melinda Wenner Moyer: There's a lot of different ways to look at this question, which is kind of a central claim made by the gun lobby that more guns in the hands of good guys will keep you safer. But when you look at the question from a lot of different ways, it kind of all comes out the same: which is that, no, owning a gun, keeping a gun in your home, carrying a gun, none of those seemed to make you safer.

KQED: Talk about some of those conclusions.
Moyer: There's been research showing that if you keep a gun in your home, that doesn't actually reduce your risk of gun violence. It actually makes you more likely to be a victim of crime or homicide or suicide. There's also been research looking at concealed carry rates. As those have gone up in some states, have there been drops in crime and in violence? And they found largely, no. There's been some research by some controversial researchers that points to possibly, yes. But it's really largely been refuted in recent years. And then there's really the central question of, if guns are protective then that implies that Americans are using the guns for self defense all the time. And the research there also suggests that actually guns are used for self defense in less than 1 percent of all crimes that occur in the presence of a victim. People aren't really getting the chance to use their guns for protection anyway.
KQED: Gun ownership doesn't make us more safe. Does it make us less safe?
Moyer: Yes. That is what the research largely suggests. It makes us less safe.
KQED: What accounts for that? Is that because if there's a gun around, then I'm more likely use it to hurt myself or hurt another person?
Moyer: Well, certainly the suicide becomes much more likely and much more, unfortunately, sort of successful when you own a gun. But really scientists are trying to figure out exactly why this is. It could be that when you own a gun you might take a few more risks, you might go to places you might not otherwise go without your gun. You might sort of end up putting yourself in riskier situations that put you ironically more at risk for crime and violence. There could be a lot of different reasons here, and it's really hard to tease out and that's one of the reasons we need more or better research to really understand what's going on.
