Illinois has passed a concealed-carry law, and it contains no provision for Chicago to opt out. In fact, the new law specifically forbids home rule units such as Chicago from regulating, transporting, or carrying weapons. Finally, it looks as though people will have an opportunity to fight back against gun-slinging Chicago thugs.
This development should provide a reasonable test, in the most dangerous city in America, of the hypothesis that an armed society is a polite society. Thus far, during the first month of 2013, some 42 people have been killed in Chicago; it'll be interesting to see how the annual tally stacks up this year, as compared with 2012, when nearly 500 people were murdered.
