Neccesity is in the eye of the beholder.
I can't imagine anyone is in such dire need of diapers that they must steal them the day of the storm. They ran out and exhausted all other legitimate opportunties to acquire them in less than 24 hours?
If the lady had stolen only one pack of diapers, it might have been needed, still wrong. But the lady I saw on camera had a years worth of the poop catchers, hardly justifiable.
