NEW ORLEANS, AFTER LEVEE BROKE

It was a mistake to breathe a sigh of relief when the storm passed, because the worst was yet to come. Although New Orleans escaped from the worst-case scenario of being flooded from the ocean due to storm surge, it was flooded from the other direction, as the rain-swollen lakes and rivers (particularly Lake Pontchartrain, which is almost as big as a Great Lake), overflowed. New Orlean's levee system was unable to handle the strain, and one of the levees broke.
Steve Gilliard has several articles about the aftermath of Katrina, including the discrepancy between the way the media describes black and white victims. He shows two different news service photos, one showing a black man wading through water with a bag of groceries, another showing a white couple wading through water with a bag of groceries. The first picture's caption: "A young man walks through chest deep flood water after looting a grocery store...". The second picture's caption: "Two residents wade through chest-deep after finding bread and soda from a local grocery store...".
