If there is hope has a good post up about “looting” in New Orleans.
Personally I don’t consider taking food, water, medicine, or other necessities under these conditions “looting” - I think anyone who does is a hard hearted lout indeed. Given those circumstances I most certainly would take what I needed, it’s called survival, and I’d take stuff for others who couldn’t get it for themselves.

Unfortunately, people aren’t just taking food, and that’s what’s downright shitty. People are stealing sneakers and stereos and looting slot machines in casinos.
That’s just wrong.
Food? I can easily forgive it. Hell, it’s not like the owner of the store is gonna get back and find all his food there and ready to sell.
