The man heading the military operation in New Orleans says if the emergency work were easy, it would have been done already.
Army Lt. General Russel Honore tells CNN the high water near the convention center and Superdome is making it tough for troops to get in. But he says they've been unloading trucks full of food and water, and will go restock when they're empty.
Honore says they'll also clear areas for helicopters to conduct medical evacuations.
The commander says he knows people in the area are frustrated at the pace, and he is too. But he downplayed talk of mass criminal activity in New Orleans, saying most of the people massed on the streets are families just waiting to get out of a bad spot.
