ERIE, Pa. (AP) -- Police have cited eight people for violating a northwestern Pennsylvania city ordinance banning guns in parks during a rally in support of open-carry laws. Twenty-six-year-old Justin Dillon, of Erie, organized the June rally and tells the Erie Times-News (http://bit.ly/15p8PEB) he was one of eight people cited. Before the rally, Dillon sued claiming the ordinance was illegal under the Pennsylvania constitution and the Second Amendment of the U.S. Constitution. An Erie County judge refused to grant an injunction preventing the city from enforcing the ordinance and a state appeals court upheld that ruling. Despite that, many of the 80 rally attendees carried guns anyway and were cited after police determined their names using vehicle license plates and other means. They're due in court Aug. 19 and face fines up to $300.
