BLACKSBURG, Va. (AP) - Former Homeland Security Secretary Tom Ridge says he doesn't think the massacre at Virginia Tech could have been prevented. But he hopes an investigation into the tragedy will find ways to reduce the risk in the future.
Ridge is among those who will be conducting the investigation at the request of Virginia Governor Tim Kaine.
Ridge told C-B-S' "The Early Show" there are lessons to be learned from this "national tragedy." But he says the last thing anyone wants to do is turn universities and public places into "armed fortresses."
There were plenty of signs that the shooter, Cho Seung-Hui, was deeply disturbed. And there have been complaints the university didn't do enough to warn students after the first victims were killed on Monday.
Two hours after two students were shot to death in a dorm, Cho stormed a classroom building, killing 30 students and teachers before turning the gun on himself.
