From The Atlantic:

Miles’s law states, “Where you stand is based on where you sit.” In other words, your political opinions are shaped by your environment and your experience. We’re products of our place, our time, and our people. Each of these things is far more important to shaping hearts and minds than any think piece, any study, or certainly any tweet. And it strikes me that many millions of Americans don’t truly understand how “gun culture” is built, how the process of first becoming a gun owner, then a concealed-carrier, changes your life.
It starts with the consciousness of a threat. Perhaps not the kind of threat my family has experienced. Some people experience more. Some less. And some people don’t experience a threat at all—but they’re aware of those who do. With the consciousness of a threat comes the awareness of a vulnerability. The police can only protect the people you love in the most limited of circumstances (with those limits growing ever-more-severe the farther you live from a city center.) You want to stand in that gap.
