Man, sad segment earlier on CNN about a trapped hospital in New Orleans that who's remaining medical staff and patients are stuck with no running water or power, and the food supply is about over. Dr. Gupta(the network's medical correspondent) flat out told of how people at the hospital keep asking other this:

"If journalists and reporters can easily come down here, then why hasn't the National Guard come in yet?"

Of course, sporadic visits from the Guard have come, but ususally the location seems to be on its own, and of course the fear of having to deal with the armed bands of looters roaming the city.
