http://www.miamiherald.com/news/breaking_news/story/438888.html Within hours of Friday's lunch-hour melee in a courtyard at Miami Edison Senior High, community unhappiness with how police and school officials reacted was beginning to surface. The disturbance followed a sit-in demonstration held during the school's first lunch block about 11:30 a.m., schools spokesman Quintin Taylor said. They were protesting the treatment of an Edison senior who was arrested at school Thursday. At least 10 officers were treated at the scene for minor injuries, said Miami fire rescue spokesman Lt. Ignatius Carroll. Six to seven students were also treated on site for minor injuries and respiratory problems, ''but the numbers seem to be growing,'' he said.
