Nice shot at alarmist healines... Personally I prefer to try to draw folks in with that funny headline... but that also can backfire.
What people need to realize (including the good mayor of New Orleans) is part of declaring a "mandatory evacuation" is deciding what services (if any) will be left intact in the disaster area. While I take every opportunity I can to mock Mayor Nagin for his completely innane and unauthorized "Martial Law" declaration, it is completely within his authority to decide what services to discontinue.
