OpinionJournal on the chaos:
One frequent reaction we heard yesterday is that the disorder in New Orleans is typical of Third World countries, something that was thought could never happen in America. This happens to overlook a fair chunk of U.S. history, some of it relatively recent, including riots and violence. But it is also a sign of complacency born of prosperity and the resilience of our legal and civic institutions.
This battle of New Orleans should remind us that civic order, even in America, is more fragile than we like to think. After this week and amid the continuing threat of terrorism, our political leaders at all levels are going to have to think harder about how to maintain order in the next crisis.
