You cannot own, possess, keep, store, carry, use, borrow, hold or fondle a handgun in those cities.
Are there exceptions? Of course. Cops, aldermen, other city officials, their bodyguards and, of course, the thousands of criminals and gang bangers. But I'm talking about the general public.
There was a recent story of a homeowner in Wilmette who shot a burglar as the burglar entered the house. The homeowner was arrested for possessing a handgun.
Serves him right for not using a 12-gauge!
