Silver Lining
What is going on now is tragic, but at the same time why were these people still there? They had a minimum of 72 hours to leave...the loss of life could have been significantly less, but the property damage would have been the same. I feel really bad for the kids that got caught up in this, especially the ones who weren't evacuated for whatever reasons.
The silver lining here is that, like a forest fire, when the water subsides the cities of New Orleans and Biloxi will experience a rebirth. New architecture, infastructure and hopefully new, stronger levees. They'll get insurance money and FEMA aid to re-build and a nation of private citizens will open its wallet to lend some aid to help out. The New Orleans of 10 years from now will still have its history, though some old buildings will probably need restoration...but nothing motivates Americans to save something that we never cared or thought about before, like a tragedy.
