[Via hakank], Interesting paper about riots in LA and Schelling's focal points.

As we saw in the case of Los Angeles, riots do not occur everywhere at once. Most of the homes and businesses in south-central L.A. and Koreatown (which cover a number of square miles) were untouched by the riot. Damage was concentrated at certain intersections and along certain strips, what we call ``action nodes.'' How did the rioters know where these action nodes were?(...) We cannot say how a resident of South-Central L.A. might go about selecting a focal point. In fact it seems consistent with Schelling's experiments that there would have been a number of focal points, although substantially fewer than there were residents. For example, any of several major intersections, parks or schoolyards may have seemed the natural place for a large number of riot-disposed people to gather following the acquittals in People v. Powell (the original Rodney King beating case), which amounted to a Schelling incident at least in part because for weeks it had been advertised as such by TV and newspaper accounts of the trial.
