I don't think this 'study' will apply to what we are seeing/hearing about this tragedy.
It's not just NO......sad to say reports from MS said looters were in action before the storm had even passed....& now looters climbing over bodies (in houses) to loot these same houses.
I think it applies for the same reasons. The smarter people ran. The criminals stayed to exploit the situation. If the hurricane hit when the area was fully populated with a full spectrum of different types of people, I think it would have much less disorder.
