The theory, I think, is that openly carrying a firearm is intimidating to others and/or appeals to people who want to posture and look tough/dangerous. Maybe a fuzzy line between carrying openly and "brandishing" - how do you interpret someone touching the butt of his gun, gesturing toward it, pointedly turning to expose the gun, etc?

In theory, a concealed firearm cannot be used to intimidate or posture, since the license requires that no-one know you are armed.

I haven't thought real hard about whether this theory is valid, but I tend to agree with it. When my wife and kids are out and about, I don't really want them surrounded by gang-bangers displaying their weapons. Also, I don't see how a law-abiding person benefits by carrying openly. Besides ensuring that you're the first one to be shot in an armed robbery.
