CENTRAL ISLIP - What began as a peaceful student protest at Reed Middle School in Central Islip against education cuts ended in a walkout and suspensions for some of the event's participants. About 200 students walked out of school to protest budget cuts and teacher layoffs. The Central Islip School District stands to lose $5.7 million in state aid, and up to 154 teaching positions could be cut. Today's protest stopped traffic in front of the administration building on Wheeler Road. Police and security guards rushed to the scene, but the students remained defiant. Some parents and PTA members arrived at the school as soon as they heard about the walkout. They told the students to return to class and let the parents take up the budget battle. "My thing to them was, this is not their fight," says PTA President Dunia Mars. Mars says many of the students who participated in the walkout received a one-day suspension, but police say no arrests were made. The PTA is calling on parents to attend a budget meeting Monday.
