The problem with what you are saying is that there isn't anyone they could sell the TV to to convert it to cash for food or a warm bath. A looter is a thief. Maybe the thief was held in check under normal conditions before the storm, but looting of TV's, appliances, high ticket items, etc. is labeling them for what they are...... a thief.
There is no electricity in the areas where the looting is going on. Who is there that would buy the television from this looter? A thief is a thief in normal conditions or in a disaster. One is no better than the other. There is no running hot water for a bath unless you leave the area. You can't buy one in New Orleans for any amount of money if you DID sell something you stole.
I don't have a problem with people entering grocery stores for bottled water, soft drinks, canned goods, etc. that they need to survive. If assistance for you has not arrived and you have hungry people, they need to use their wits to get necessities to survive. But it is possible to keep some respect for others and their property & to shame others that you see entering homes to loot them, stores, apartment buildings, etc.
My heart goes out to all the people who are suffering in that area. The minority of the people are the ones who are doing this, but they seem to get the maximum coverage from our sensasionalist news media. They are out there looking for anything they can find to shock you.
