How is it considered "looting" when people go into completely ruined buildings to retrieve water and other life-sustaining objects? If you were in an airplane crash and survived and took food and water, blankets, and whatever else might help -- would it be called "looting?" I don't think so.
This happened during Katrina as well. People who felt abandoned broke into already broken stores to sustain themselves.
I see this as salvaging what might help. Words matter. Comments?
