A Milwaukee man only recently acquired his permit to carry a concealed handgun and then found himself in the middle of an armed robbery. As the robber threatened a store clerk with a shotgun, the permit holder was able to draw his weapon and shoot the culprit. The Milwaukee District Attorney said: “He disrupted an act that potentially exposed himself and others to great bodily harm.”

Last week, Cato released a new study concerning the frequency with which citizens use guns in self-defense, along with a map to track such events. We’ve already received many suggestions from readers all over the web and we’ll be updating our map regularly.
