For years I lived in the in the most densely populated area of Los Angeles -- the Westlake District, or Rampart District as it came to be known after the LAPD "gangsta cop" scandal. It's the area that the TV series "The Shield" is set in.
Now I live in the hills of Montana. It's better.
These two areas have two very different schemes of gun control, and each strikes me as appropriate to its environment.
Here in Montana, you can carry a gun pretty much however you want and wherever you want, and even the modest restriction for cities (a shall-issue CCW is required) is currently on the chopping block in the legislature. Despite these liberal gun laws, the murder rate is not out of control. People are not constantly shooting at each other. There are no gunfights on the streets.
In Los Angeles, an individual's gun rights are so obscure that most people opt not even to own a handgun, let alone try to carry one, even in their cars. And this is good. Because there are four times as many people in the city of L.A. than there are in the entire state of Montana. An apt comparison of the population density would be a can of sardines versus those same sardines spread out in the Great Lakes.
Oh, and in the Rampart area of L.A. -- people are constantly shooting at each other. This is not an exaggeration. When the gangs were really fighting, I'd hear more than one gunfight a night. The kitchen window of my apartment had a bullet hole in it, and I lived on the eighth floor.
Nobody I knew cried much for an 18th Street Gang member who got killed trying to assassinate a rival, or, especially, a cop. But innocent bystanders are a different matter. When an innocent child (and an alarming amount of the time it is a child) is gunned down just because she happened to be waiting for the bus when a gunfight broke out nearby, the community cannot help but think, How can we stop this from happening?
And, understand, they sincerely want a real answer to that question -- a real, effective answer that will actually reduce the number of innocent people in their community getting killed and maimed as collateral damage in the gang wars.
"Everybody should have guns" is not the answer. It is, in fact, an offensively stupid answer that can only be promoted by someone with a poor understanding of urban crime and no skin in the game. In the (non-hypothetical) example above, the gunfight broke out between two or more gangbangers who did have guns. They were shooting at each other. Arming the kid who died, or her mom, or everyone at the bus stop, would not have prevented the gunfight or reduced the death rate. Among the people who actually live in these communities, the answer to those who provide "Everybody should have guns" as a solution to the innocent-bystander problem is, quite understandably, "f--- you."
"Enforce existing gun laws" is not enough. The LAPD enforces every gun law it can. Catching a gangbanger with a gun, in fact, is a principal means of getting criminals off the streets in L.A. You don't even have to catch him committing the robbery he just did or the murder he was just about to do -- you only have to catch him with the gun to put him in jail (he almost certainly has a criminal record making it illegal for him to possess the gun). Still, the gang wars rage on, and innocent people die literally every day in the crossfire.
"Reduce availability and potency of guns," a solution far from adequate, is nonetheless the best anyone's been able to come up with to deal with the problem of gun violence in extremely densely populated cities. We know that the gun-control laws against fully automatic weapons work. If the 18th Street Gang could get or make automatic weapons to use regularly on the street, they would. But it's too hard to be worth it, and the law is what makes it too hard. And it's obviously good that the gunfights on the streets of L.A. are not being waged with automatic weapons. So the community naturally thinks, How about continuing in this proven direction?
Obviously, this is problematic, as we Montanans don't want to be restricted by the gang wars of L.A. We don't have daily gun battles here. What's good for the Rampart District is not good for Montana.
But the question was...how do you talk with people who favor more gun control? I think a prerequisite is understanding that "more gun control" is not their main purpose. "Ending collateral damage from out-of-control gunfights in the inner city" is the purpose of the gun-control advocates I knew in L.A. If you have a better solution to that problem, they're all ears. But if you instead insist on caricaturing them as mindless zealots with no real reason for the gun-control position they have, well, they know better, and they'll rightly pay you no attention.
