From Detroit Free Press:

…a federal appeals court panel’s divided ruling last week in a California case makes it more likely that the question of guns outside the home will be heading to the high court soon.

To date, the biggest split from that trend involved an Illinois law that was much more restrictive than those in other states. Its ban on carrying concealed weapons in nearly all circumstances was struck down by a 7th Circuit appeals court panel. Rather than appealing to the Supreme Court, however, the state amended the law to allow for public possession, with restrictions.
