 EARLIER THIS WEEK, HELICOPTERS SCANNED FOR RADIOLOGICAL AND NUCLEAR MATERIAL. WISCONSIN STATE LAW PROHIBITS THE CITY FROM BANNING GUNS WITHIN PARTS OF THE SECURITY FOOTPRINT SURROUNDING THE CONVENTION. IN THE SO-CALLED HARD ZONE SEEN HERE IN RED, CLOSEST TO THE CONVENTION HALL, NO GUNS ARE ALLOWED. BUT JUST OUTSIDE THAT ZONE SEEN HERE IN YELLOW, PEOPLE ARE PERMITTED TO CARRY LEGAL WEAPONS.
