"It's perfectly normal," said Tom Sweitzer, the group's leader. "It makes sense that anxiety would creep its way in."

Evan Knapp, a Perry Hall senior, lamented that such shootings have started to seem commonplace, but urged his classmates to grow from the tragedy. "It's just the world, so you've got to overcome it," he said.

Others said they saw the tragedy as a fluke that could have happened anywhere.

"I don't know how much more they can do," said Michelle Cody, a Perry Hall junior. "I've always felt safe."
