If you live in that area, none of this is news. There have even been treatsies and essays written on the city's rather schizoid personality. One face is that of the care-free party animal, the others is that of the murderous thugs. Racism, poverty,reverse-racism, classism, ignorance, indifference, sloth, and greed all had a hand in making the dangerous stew the nation at large saw for the first time last week on their TVs, but which the natives of NO were all too aware of.
Most people think of/thought of New Orleans as a party city. Some place to go to have a good time and drink and enjoy themselves. Most rarely stepped outside the French Quarter. And few were aware of its crime rates, unless they happned to get mugged while visiting. While I lived there it was both hte Rape Capital and Murder Capital of the US. Which was rather sobering, given its relatively small population, compared to say Dallas or Atlanta or NYC. The very ugly truth behind the carnival mask must be a serious shock for most Americans, not to mention visitors from abroad.
