I don't know. How hard would it be to fly them to safer grounds. When you have that many people in a place without sewer you run a risk for all kinds of diseases. If the water is continuing to rise they are in danger of drowning too. These lawless are going to need food and water soon,also. Would it not be best to do both. Roof rescue and dome evacuation and leave the looters ?
ANother thought that popped into my mind...THE Army is able to lay temporary bridges (for moving troops) in a matter of minutes....Wonder if we'll see something like that done...With the folks walking out to board buses.
