In largely rural states like Indiana, where I live, response times can be 30 minutes or more. Maybe that’s why nearly a million Hoosiers hold active gun permits, as per state records, out of an adult population of 4.5 million.

I’ve been one of them for decades. I’ve gone Christmas shopping armed, carried at family outings, sporting events and movie theaters. I was fired from a job with the gun tucked in an ankle holster. Aside from the indignity of being fired, the only person in danger was me, when I broke the news to my wife.

Indiana assumes—in the absence of evidence to the contrary—that people will protect themselves without reflexive, wanton violence. It works. A gun-use Venn diagram would show a mere sliver of overlap between those who lawfully carry weapons and those who use guns in the commission of crimes. You don’t find National Rifle Association stickers on getaway cars.
