You could imagine the fear that students felt. Unfortunately, the image of seeing a campus paralyzed by fear is one that has been replayed on television too many times. But the good news is that no one was hurt at Cal State. In fact, the 'perp' didn't even have a gun. What happened was that a construction worker's Samsung Galaxy handset was mistaken for a weapon. Hard to see where that mistake could have been made, but we are thankful that this didn't end up turning out badly like many of these situations do.
