There is nothing inevitable about gun violence. And while the scandalously high rates of murder in both Brazil and South Africa are treated by many as "normal," there are encouraging signs of change.

Australia's gun buyback program reduced the country's firearms stock by about one-fifth, which is equivalent to the U.S. reducing its national stock by 40 million guns. And while some weapons came from households with multiple firearms, survey evidence suggests that the buyback nearly halved the share of Australian households with one or more firearms.
