The Volokh Conspiracy has us figured, I fear:
When I lived in New Haven and watched the New York TV news, I was struck by the different assumptions about city problems in NY compared to Chicago. In Chicago, the mayor takes the credit and blame for everything, and the news media assume that the mayor should stop every major strike, even private sector ones. In Chicago, the mayor is “Big Daddy.” While one, of course, sees some of the same in New York, there is still a significant difference of degree. New York being less provincial than Chicago, sometimes the news media actually assume that New York City departmental personnel are responsible [or treat major local events as being outside the local government's scope of responsibilty].
