Given a choice between their worldview and the facts, it's always interesting how many people toss the facts. Right now, the United States is plagued by an army of "birthers" who claim that because Barack Obama was not really born in America, he's not legitimately president. Their evidence is non-existent, their arguments loopy, but people who find our non-white president unacceptable would rather scour the Hawaiian medical records system and invent bizarre theories than face their own internal turmoil. Or racism.
What people were willing to believe about Hurricane Katrina in New Orleans four years ago is a more serious matter. Of racism. And cliche. The story, as the mainstream media presented it at the time, was about marauding hordes of looters, rapists and murderers swarming through the streets. The descriptions were pretty clearly focused on African-Americans, the great majority left behind in the evacuation of the city (which was then two-thirds black anyway).
There were supposed to be a lot of murder victims and murderers in the Superdome, the sports stadium the city opened up as a refuge of last resort. The rumours were believed so fervently that they were used to turn New Orleans into a prison city, with supplies and would-be rescuers prevented from entering and the victims prevented from evacuating. The belief that a Hobbesian war of all-against-all had broken loose justified treating the place as a crime zone or even a hostile country rather than a place in which grandmothers and toddlers were stranded in hideous conditions, desperately in need of food, water, shelter and medical attention.
Louisiana's governor at the time, Kathleen Blanco, announced as she dispatched National Guard troops: "I have one message for these hoodlums: these troops know how to shoot and kill, and they are more than willing to do so if necessary, and I expect they will." She and the city's mayor had called off the rescue efforts to focus on protecting private property – with lethal force if necessary. The sheriff of the suburb across the Crescent City Connection bridge from downtown New Orleans turned back stranded tourists and locals at gunpoint. "As we approached the bridge," wrote two stranded paramedics, "armed Gretna sheriffs formed a line across the foot of the bridge. Before we were close enough to speak, they began firing their weapons over our heads."
