The Volokh Conspiracy has some thoughts on gun control and compares it to another time the US banned something entirely:

If you added in gun suicides on one side and those people whose alcohol consumption killed themselves on the other, the deaths would tilt much more on the side of alcohol use, but I generally like to segregate deaths of the user from deaths of others.

So what are we going to do about it? When are we going to ban alcohol? When are we going to institute more common-sense alcohol-control measures?

Well, we tried, and the conventional wisdom is that the cure was worse than the disease — which is why we went back to a system where alcohol is pretty freely available, despite the harm it causes (of which the deaths are only part).

He ends with this (which should be engraved into the legislative bodies of all 50 states, DC and the US protectorates, as well as Congress):

We should certainly consider proposals that aim to ameliorate the problem, and weigh their costs and benefits. But we should not presume that there’s somehow a moral imperative to Do Something. In fact, there’s a moral imperative not to do something that’s likely to make matters worse.
