At least in Chicago, "everyone that can carry" consists of LEOs and licensed security workers on the job. That's not very many people. Of course, a fair number of gang-bangers will be carrying, as well. I grew up in the suburbs of Chicago, and the only people I knew who carried firearms were cops. The idea of an average joe carrying was such a foreign concept that the local news did a special story on it when they found someone who figured out the "unloaded concealed carry" loophole. The news wasn't going with the "look at this intelligent guy" angle either!
