As long as the politicians in Cook County (and, to some extent, the collar counties*) are calling the shots, Illinois will never have CCW. Their inability to keep their house in order is reflected in the approach that it must be the guns coming to Chicago from outside that's the problem, rather than examining their own bailiwick. Therefore, no one but sworn LEOs can carry in IL. These people have even attempted to exert pressure on the government of Indiana to establish a higher level of gun control.
*For those reading this thread who may not know, the term "collar counties" in IL refers to those immediately surrounding Cook: Will, DuPage, Lake, McHenry, & Kane.
