I often hear/read an argument for firearms that doesn't hold water. It is made by our camp, and while I agree with the conclusions, I don't think the argument supports them.
The statement is that crime is higher in places where guns are outlawed (D.C., Chicago, etc.) and lower in places where guns are allowed (Utah, Idaho, etc.). This is a statement of fact, and is only the foundation of the argument. It is the next step that bothers me -- that because of the fact stated that guns decrease crime. In other words, people use the idea that Chicago outlawing guns and Utah supporting guns causes more or less crime. While I do think this is true, the fact alone does not logically prove causality.
The reason it doesn't hold is D.C. and Utah are two very different places. D.C. is inherently more prone to crime than Utah is (for many reasons). Firearms are only one piece of a very large pie of reasons. It could very well be that D.C. might even have more crime if it allowed lawful firearms. It could be that allowing firearms in D.C. will decrease crime. The point is that comparing it to the way things are in Utah is a pretty weak argument.
This is no different than comparing the sales at a McDonalds in D.C. with sales at a McDonalds in Utah. One of them might be in a high traffic area, one might be in a low traffic area. One might be very well run, one might be terribly run and horribly dirty. One might be on a freeway, one might be in a mall. One might say that the D.C. McDonalds has higher sales because it gives better coupons, but so many other things are varying that the argument doesn't hold. To know if one thing causes another, you have to hold all else constant (as much as possible), show that one precedes the other in time, etc.
The better comparison is to show that D.C. has higher crime than Virginia -- right across the river. If the two are very similar places (which I think they are), and that part of Virginia has lower crime than D.C., then the argument is more solid. Firearms--being one of the primary differences--are a likely cause of the difference. An even better study would be to watch crime in D.C. when they are allowed again. It's a great longitudinal study.
I DO believe that firearms in the good guy's hands (i.e. general population) decrease crime. We have some great data supporting our position. I just get tired of hearing an argument from our camp that is logically flawed when so many better arguments are there.
