Dozens of bomb threats at the University of Pittsburgh, including at least four on Monday, have made professors start holding classes outside and forced security officials to put in new building access measures and offer a $50,000 reward for information.
Some students "are definitely afraid," said Brian Haughwout, a junior who had one of his final exams changed to a take-home because of the disruptions.
"But I think just shutting down the university would be a mistake," he said, adding that's probably what the person making the threats wants.
