NEW YORK - Anti-war activist Cindy Sheehan said Tuesday she was hurt slightly in a scuffle that erupted when police broke up a rally as she was at the microphone. An organizer was arrested and charged with using a loudspeaker without a permit. “I was speaking and someone grabbed my backpack and pulled me back pretty roughly,” Sheehan said, describing the scene at Manhattan’s Union Square on Monday. “I was shoved around.”
