I thought the McDonald case established the right to bear arms outside the home? In fact, I believe it was the basis for forcing illanoy to finally enact concealed carry.
No, McDonald did not clearly establish the right to bear arms outside the home.
It was the Seventh Circuit in Moore v. Madigan.
That case followed McDonald, which established that the Second Amendment applied to the states.
But, Moore v. Madigan helps establish the split in the Circuits.
