In the case of the Superdome, they're being held back by barricades and armed soldiers. The area is also still flooded. You won't get very far in 95-degree heat without drinking water and when some of the water is up to your waist. The area is devastated for miles around.
I think it's worth keeping in mind that if you think there's an easy solution, but people are too stupid to take it, that some of your assumptions are faulty. People are not naturally inclined to suffer and die. They don't want to be there.

Agreed. So what is the actual situation? Is there really some reason news people can get in and out, but nobody can bring in food or water or take anybody out?
Hard to believe. No?
