Only two of the 18 people arrested Wednesday during a demonstration related to the Republican National Convention gave Ohio addresses - Steven Fridley of Poland, Ohio, and Dominique Knox of Cleveland Heights. Fridley, 23, is accused of failure to disperse, aggravated disorderly conduct and resisting arrest. Knox, age unknown, is charged with assault on a peace officer, obstructing official business and resisting arrest. Names and addresses released by the city Thursday show another of the arrested demonstrators is from Australia and that others arrived here from across the nation - New York, Chicago, San Francisco. All were arrested following a flag-burning demonstration organized by the Revolutionary Communist Party. The demonstration was led by Gregory Johnson, who was at the center of a 1989 Supreme Court ruling that established flag-burning as protected speech under the First Amendment.
