To forestall what I expect will be many, many making the same point:

Mr. Derb,
Listening to Radio Derb right now. As you have probably heard 1 million times already, no one was carrying a gun in the mall because it was illegal to do so. While Omaha has a concealed-carry law, the mall itself is a “gun-free zone.” As were the mall in Salt Lake City and Virginia Tech’s campus, which both had their own recent massacres.

[Me]Thank you, Sir. I missed that, though I am not surprised to learn it.

Perhaps if we could get Mr. al-Maliki to declare Iraq a “gun-free zone,” the ructions there would cease, and we could bring our troops home. Why hasn’t anyone thought of this?
