I believe in mandatory evacuation. When a disaster like this strikes the only logical thing to do to maximise resources and minimize casualties it to have a full on military evacuation of those who dont wish to leave. Get the fucking tourists out, get the citizens out and let the only damage be to structures from the storm.
This leaves no people stranded, no looters, no riots.
Anyone who refuses to go is either dragged by their balls or left to die with no aid after the fact.
I realise that most of the people who are stranded now simply couldnt get out or were evacuated to unsafe areas. If this were done with a zero tollerance for leaving anyone behind we wouldnt have the horrible situation that is reality now.
Its costing more in monetary and human measures to try to fix shit up and finish the job after the storm passes.
Pull everyone out of harms way whether they want to go or not and keep them safe. Then concentrate efforts on rebuilding.
This chaos will create a standard protocol for future disasters that will leave little room for the shit we see happening now.
