The state could pass an emergency law authorizing the Salvation Army and similar agencies to pass out the food that would have otherwise been trashed, and also immunizing same from any liability for the food.
You bring up a good point. Some of these looter are so corrupot, they might claim food poisoning either from the looted food, or from what is provided by relief agencies. The the lawsuits will fly and that part of the country, juries ahve been traditionally very sympathetic to the poor plantiff. That's in the area where all the class action lawsuits get tried because the juries are so generous.
