According to almost every major study on the issue, Americans use their firearms defensively between 500,000 and 3 million times each year. From @HeritageDataViz

This is a database of incidents where armed citizens used guns against bad guys-- burglars, muggers, would-be kidnappers, etc.
It's got a map, which you can zoom in or out, to focus on a particular area. Dots are shown for each incident, and clicking on the dot makes more info pop up with the details of what happened. Pretty cool.
