How can this happen?

Armed looters in the streets, shooting at the police and helicopters.

A sniper taking potshots at a hospital with 200 patients waiting to be evacuated.

Men robbed and women and girls raped in the bathrooms at the convention center; now people defecate on the floor rather than risk using the bathrooms.

Bodies riddled with bulletholes; a man with his head shot off.

I can't believe this is happening in the USA. It's difficult to believe that people can sink so low as to prey on the victims of Katrina. As one source said, when the Tsunami hit, the people helped each other, but that's not happening here. As Louisiana Governor Kathleen Blanco said:

What angers me the most is disasters tend to bring out the best in everybody, and that's what we expected to see. Instead, it brought out the worst.
