A federal court ruling tossing out Illinois' ban on concealed weapons might end the last such gun prohibition in the country, but not without an expected fight. The question is whether the battle will be an appeal to the U.S. Supreme Court or a legislative confrontation over the court's order that Illinois adopt a law allowing concealed carry with "reasonable limitations" like other states have. Illinois Attorney General Lisa Madigan's office says she is studying the issue, while gun control advocates quickly urged her to appeal Tuesday's ruling by the 7th U.S. Circuit Court of Appeals that Illinois' ban is unconstitutional. More certain is a confrontation over the order for the Illinois Legislature to come up with a law legalizing the concealed carry of weapons within 180 days.
