Don't get your hopes up, Illinois gun owners. They'll probably pull a "Jersey" on you, requiring that you prove a "need" to carry. But unless you are a LEO or RAT connected, the proof will never be sufficient.
It's possible they may try, but the Court clearly indicated that it would consider a discretionary permitting system like NY's to be inadequate.
I'd think a shall-issue law that exempts Chicago to be more likely.
Meanwhile, does anyone know what's going on in Maryland?
Why do you think that? I don't see any indication in the court's decision to indicate that somehow Chicago will be immune from the prohibitions of the Second Amendment. It was Chicago who was the defendant in the McDonald case involving guns in the home. Chicago lost.
