Many decided to leave after the harrowing incidents. "They all want to leave. They were traumatised and people were saying, 'I want to get home'. "South Dublin is a small parish, all the schools know each other, they play against each other, they are friends with each other, and there are older siblings and friends all over the area who are deeply devastated. He said pupils are "traumatised". "They just want to come home and will be all home in the next 48 hours."
