ROBERT SIEGEL, HOST:
These are strange days at the University of Pittsburgh. Since mid February, the school has received more than 50 bomb threats. While they've all been false alarms, they have succeeded in disrupting campus life. Tighter security measures are now in place but the threats continue.
And as Larkin Page-Jacobs, of member station WESA reports, students are wondering how they'll make-up class work and prepare for final exams.
UNIDENTIFIED MAN: Come in the doorway. If you have bag, stay to the right. Have your bag open, I.D. out. When you hit the steps, please...
LARKIN PAGE-JACOBS, BYLINE: At first, sophomore Maggie Stankaitis thought the threats were a response to the unseasonably warm weather; some prankster student trying to get out of class to enjoy the sunshine. But now, dozens of bomb threats later and with lines of students backing up to get to class and the library, she's changed her mind.
MAGGIE STANKAITIS: I'm like kind of waiting for it to happen. I have, like, an emergency bag packed if I need to be evacuated.
PAGE-JACOBS: Initially bomb threats appeared scrawled in bathroom stalls in the towering building called the Cathedral of Learning. But lately they're being sent over the Internet, using a method that makes them difficult to trace. A joint-terrorism task force - including the FBI, Department of Justice and campus police - is investigating, says University spokesman Robert Hill.
ROBERT HILL: We are obligated to treat every threat seriously. We search. We clear the building. But now, when we clear the building and make it available for occupancy, I.D.s are required for admission.
PAGE-JACOBS: Around 29,000 students attend Pitt, and every threat is followed by an evacuation - whether it's the 42-story Cathedral of Learning or a dorm at 4 A.M. And Hill knows the experience is unnerving for students.
HILL: There hasn't been a bomb. There hasn't even been a device detected. Still, it's unsettling to have been subjected to the threats.
PAGE-JACOBS: Sitting outside the student union, junior David Giannaula says he's experienced a range of emotions about the threats.
DAVID GIANNAULA: I wrote it off as someone getting out a test. And that was like the first two weeks because they happened at similar times, and everything. And then I got annoyed. It was just like, these are fake, I'm tired of it. And then, actually like about the last two weeks, it's been a bit more nerve-wracking because it just like isn't stopping at all.
PAGE-JACOBS: But junior Corinne Hogge thinks that fear plays right into the hands of the person, or people making the threats.
CORINNE HOGGE: I feel that unwarranted fear just causes chaos and that that's what this person wants.
PAGE-JACOBS: So she's trying keep a lid on it. But as she's watched her classes cancelled or interrupted, she can't help but feel ripped off.
HOGGE: It's just kind of upsetting knowing that I worked an entire semester and that, you know, finals may be optional or I may not do as well just because I didn't have the opportunity to have the class time.
PAGE-JACOBS: Lawrence Likar, a retired FBI agent and professor at La Roche College in Pittsburgh, says the university has to strike a balance, as it takes into account students, academics, and worried parents.
LAWRENCE LIKAR: You've got enormous pressure from their loved ones. And that pressure is so important to an institution; the safety of the children, altruistically, and then from a business standpoint, there's tuition money, too.
PAGE-JACOBS: The university won't discuss what's in-store for finals and graduation. But a number of students say they're ready for the semester to end, so they can get off campus.
