Well given that there's no food, and no gas, and no drinking water unless it's provided by aid agencies, I suspect the thoughts of most people would be to find these essentials.
Anyone looting TV's will be foregoing the opportunity to get food water etc for their families and will have to carry the TV through waist high water and still not have electricty to watch them, so good luck to them. It's not a question of whether that's acceptable or not, they are to be pitied for their stupidity not scorned.
You can't buy the esentials, the shops are not open, the pharmacies are not open.
If someone puts a chair through the window of a pharmacy and steals some drugs they need then that's acceptable. Same goes for food, bottled water etc.
The number one medical problem is people needing medicine for diabetes, heart conditions and cholestorol (according to one doctor).
I suspect it's already being done in areas but the correct solution would be for the stores selling essential goods to be turned into distribution centers with food, water etc being distributed free of charge.
