I keep hearing comparisons between the London riots and riots in other European cities -- window smashing in Athens, or car bonfires in Paris. And there are parallels, to be sure: a spark set by police violence, a generation that feels forgotten.

But those events were marked by mass destruction; the looting was minor. There have, however, been other mass lootings in recent years, and perhaps we should talk about them too. There was Baghdad in the aftermath of the U.S. invasion -- a frenzy of arson and looting that emptied libraries and museums. The factories got hit too. In 2004 I visited one that used to make refrigerators. Its workers had stripped it of everything valuable, then torched it so thoroughly that the warehouse was a sculpture of buckled sheet metal.
