The problem with this whole issiue is that the Anti-Gun movement in Illinois has already summed up what it would do in responce to the passage of Conceal Carry in Illinois. It was summed up by the now departing mayor of Chicago, Richard M. Daley., who stated something to the effect ( I can't find the quote it was in the trib several weeks ago) that if people want to conceal carry handguns , they can go live in Dupage county, or Lake county or Will county or ,Kane county but NOT Cook county(The city of Chicago is in Cook county for all of you non Illinoisins).
This to me implies the intent for at the very least the City of Chicago if not the County of Cook to fight expanded 2A Freedomes on the local level and force supreme court showdowns just like Mcdonald v. Chicago.
