Since the start of the school year, cell phone videos of skirmishes at schools have repeatedly surfaced at the school. For instance, two students were arrested after one fight in mid-October, and a teacher who tried to intervene was injured. About a dozen students have been summoned to court, prompting city officials to call an emergency meeting.

As parents and teachers voiced concerns to city officials and school committee members, several parents said their children don’t feel safe at school. Measures talked about by the school committee during the meeting included a new security task force and increasing student support and counseling.
