Gun control, the limiting of gun ownership, can be supported by a very reasonable utilitarian argument. By restricting gun ownership, the likelihood of people getting injured or killed by guns is reduced. While denying people the right to own guns can be taken as a harm, this is supposed to be offset by the greater reduction in harms to the potential victims of guns (or people with guns).
In the United States, people are often inclined to view gun control as a special sort of matter rather than being a matter of general principle about the legitimate extents of liberties and limitations. On the right, gun ownership is sometimes venerated and defended with zealous devotion. On the left, guns are sometimes seen as inherently terrifying (perhaps even as mechanical monsters whose very existence threatens life and limb).
the main argument for restricting specific gun liberties or rights is to reduce or prevent harms that would be more likely to occur without restrictions. This is, obviously enough, based on the more general principle that rights or liberties can be restricted under the justification of preventing or reducing harms. As such, it would seem useful to discuss the matter of gun control in this more general context.
Given that the goal of gun control is to reduce or prevent harm, it might be tempting to argue in favor of complete gun control or, at least, incredibly strict restrictions. After all, if such a level of control could be established over the entire population, then the amount of harm involving guns would be greatly reduced. The general principle at work here would be, obviously enough, that a complete ban or incredibly strict restrictions would be justified by the fact that they would significantly reduce the harms that involved guns. While this has a certain appeal in regards to guns, it seems rather less appealing when applied to other things.
If the goal is simply to reduce the number of deaths, then gun control would be rather low on the priority list of things that need to be strictly controlled. After all, far more people perish due to automobiles, tobacco, alcohol and obesity than die in incidents of gun violence. As such, if guns can be severely restricted under the justification that doing so would reduce the number of deaths, then it would follow that automobiles should be subject to the same level of restrictions because they generate a significantly greater death toll. Also, the causes of obesity should be addressed by very strict laws regulating what foods people can purchase, consumption volumes and exercise. While some do advocate for such restrictions, most would see these as absurd. However, if banning Big Macs and cars is absurd, then banning guns would also seem absurd.
