Shoot to kill looters. And if you are my U.S. government and politics teacher, shoot to kill IF AND ONLY IF they don't respond.
Looting food, water, the necesities is fine with me, but if a kid comes out with 3 new pairs of Nike's he needs to be busted. Steal a TV and what are you gonna do with it? You have no electricity and you'll probably drop it in the water and ruin it anyway.
