From the city of brotherly love:
Tian, 19, of South Philly, and five other students who are recent immigrants are staying home today because they were among 26 Asian students who were attacked by a gang of other students throughout the day yesterday, said Xu Lin, of the Chinatown Development Corporation, who works with victimized students.District officials said that 10 students have been suspended. … The ordeal began Wednesday, Lin said, when a Vietnamese student was jumped by 14 students across the street from the school. Yesterday, the attackers were roaming the halls “searching for victims class by class during school,” he said.
I don’t understand that last part. How can they be ‘roaming’ the halls like a pack of wild dogs if there are presumably adults and staff present?
