The group Wisconsin Carry says mandatory surveillance cameras in gun shops would be a violation of gun owners’ rights.  Group President Nik Clark is threatening to file suit over the new rules requiring the cameras in those Baraboo businesses.  The city attorney says the local rules are focused on cameras only and have nothing to do with buying or carrying a gun – so, he’s confident the city would win a court fight.  Baraboo made the change after a July robbery at a gun store.
