Panic can happen even without a crowd, in wide open space, as we’ll see. But in almost every case, it is a symptom of a larger problem. In fact, the reason that so many disaster researchers are loath to talk about panic is that the word is a conversation killer. The crowd panicked, end of story. But there is a problem underneath the panic. But the problem was almost always preventable. Just like hurricanes don’t have to kill people, crowds don’t have to crush.
