Mogadishu on the Mississippi.
That's a bit unfair, uptown has remained as it's always been. You don't see this shootouts in rich areas, now do you. Haven't seen any news of crime among the ruins of Lakeview either, or the ruins of St. Bernard Parish. The crimes are all happening in what were in the former New Orleans, ghettoes often capped off by housing projects. It's not happening in the nice areas, so it's unfair to judge the whole city based by what people who used to live in the projects are currently doing.
Ouch! I like that one. Maybe it will stick.
