Nobody wants to say this and I don't want of offend. However, the people causing the problems are mostly from the poorest parts of NO. They didn't have much hope before the storm so now there is nothing to lose.
Things will never be normal for them. Its not losing a place to live, a t.v., clothes, etc. Its losing a community, neighbors, friendships, etc. Their place in society is gone. Hopefully many people will look at this tragedy and see opportunity to start new and fresh. They are going to need lots of help and care to get started in the right direction.
