This they did - in the most difficult and irritating way possible. Chicago, of course, is allowed special latitude in refusing CCW permits.
Of course, seeing as the legislation was in part crafted by those paragons of legal knowledge, Chicago Demonrats, we get this:
From the CCW Reciprocity web site (sic):
Illinois allows residents of other states carry a concealed firearm in their vehicle if they are can legally carry a firearm in public under the laws of their state or territory of residence and are not prohibited from owning or possessing a firearm under federal law.So, ANY Wisconsin resident can carry concealed in their vehicle, since Wisconsin does not require a CCW to carry a gun in public - just if you want to "conceal" it.
Smart people, those Chicago Demonrats!
Please note - you carry a gun in the People's Republik of Ill-Annoys at your own risk...even with an Illinois CCW...
