One of the biggest difficulties in modern America is bridging the urban/rural divide:

My father, living in a rural area, purchased a shotgun for home defense -- when 911 was accidentally dialed, the sheriff's response time was roughly 30 minutes. Their primary political concerns revolve around taxes and regulation. Sometimes a bear walks through the neighbor's yard.

At our house in the city, on the other hand, I can throw five burritos and hit five other residences. I can't imagine firing that same shotgun in our house, as our windows and our neighbor's windows are in direct opposition. Police response times are quick, but we have people camping in the bushes across the street, a car break-in thrice a decade, and the occasional heroin addict passed out in the park, needle still in his arm.

These are two entirely different modalities of living, and we are trying to apply federal law to both. The second amendment is essential to our democracy, but it is increasingly difficult to argue with the growing calls to address gun violence as a public health threat. Nobody wants to get shot, everyone wants to live free and out from under the thumb of a tyrannical government. We can find a way.
