CHICAGO (MarketWatch) -- The governor of Florida refused a request from the mayor of Tampa to bar the carrying of firearms downtown during this summer's Republican National Convention, the Associated Press reports. Mayor Bob Buckhorn had asked Rick Scott to override laws that allow people with concealed weapons permits to carry guns in the city, citing worries over the politically charged atmosphere. But Scott, a Republican elected in 2010, said a gun ban would violate the constitutional rights of citizens to arm themselves, the wire service noted.
