It compares the level of danger between the blackout of 1977 and 2003. It speaks about the genesis of their occurrence. Basically Greenberg thinks the residents of New York have become more civil and passionate about their city. So the thought of destroying it when it becomes vulnerable (having no lights) is abated or reduced. The blackout of 1977 was more chaotic than the one in 2003. Greenberg searches for answers for this. He applauds the greater strategic police force which influenced the demography of New York (fewer young men and teenagers in the brackets most likely to commit violent crimes).
