Taming the tools of violence.

This article summarizes why firearms are the most lethal tools of violence, and some pertinent issues public health professionals face when working to ameliorate the effects of gun violence. It surveys large gaps in data and understanding regarding the African context--most research has hitherto been conducted in developed countries. And it reviews international agreements that could be used to mobilize support for public health approaches. Although none focus explicitly on public health, some agreements offer commitments that can be used by people working to improve public health.
