I'm sorry to say this but some of the comments posted here are totally wrong and I am going to try an put the right.
The people of Louisiana and surrounding areas were without food and water for 2 days because their government and country abandened them. They did not have any aid and it was looking likely that none was coming.
These were normal people like you or I who have families, jobs and nice cars and can normally afford their own food. But what would you do if you had no money, food, water, shelter or support from your Goverment?
You surely wouldn't wait around on the edge of the street dying when there is plenty enough food inside a closed supermarket.
I know what I would do anyway..
and then there's the American Goverment who have given shoot to kill orders to their troops to kill these everyday citizens for trying to survive.
