On page 32 it talks about Chicago's restrictions on possession of firearms outside the home, but when CPD encounters anyone outside of their home with a firearm (such as in the passenger compartment of their vehicle), they charge them under Illinois UUW law - not some Chicago municipal code.
I beleive that if someone is on their front porch with a firearm, CPD still charges them under state law. Is there a case where someone was charged instead with an ordinance violation?
I guess I don't totally understand this part of it. It seems to me that what they're talking about on page 32 is what is at issue in Moore & Shepard v Madigan.
