Last week, in the shadow of the British riots, I was discussing the events with a friend of mine and he brought up this thing called the Riot Index. I’d never heard of it before, but then, the next day, there it was again. In the Globe and Mail! And then, the next week, there it was yet again on Fareed Zakaria...twice.
Essentially, the theory is that as governments cut back on social spending, there is a concommitant rise in the likelyhood of riots on the streets. I don't have anything in particular to say about this as it seems pretty commonsensical to me, but hey, thought I'd just throw that out there.
