While the Federal Emergency Management Agency fumbled about, doing almost as much to prevent essential supplies from reaching Louisiana and Mississippi as it could to facilitate it, Wal-Mart managers performed feats of heroism. In Kenner, La., an employee crashed a forklift through a warehouse door to get water for a nursing home. A Marrero, La., store served as a barracks for cops whose homes had been submerged. In Waveland, Miss., an assistant manager who could not reach her superiors had a bulldozer driven through the store to retrieve disaster necessities for community use, and broke into a locked pharmacy closet to obtain medicine for the local hospital.Meanwhile, Wal-Mart trucks pre-loaded with emergency supplies at regional depots were among the first on the scene wherever refugees were being gathered by officialdom. Their main challenge, in many cases, was running a gauntlet of FEMA officials who didn’t want to let them through. As the president of the brutalized Jefferson Parish put it in a Sept. 4 Meet the Press interview, speaking at the height of nationwide despair over FEMA’s confused response: “If [the U.S.] government would have responded like Wal-Mart has responded, we wouldn’t be in this crisis.”
