"If we had opened the bridge, our city would have looked like New Orleans does now: looted, burned and pillaged." ...I also heard this story described by someone who experienced it on This American Life yesterday. Police shot at a group of tourists trying to cross the bridge to leave New Orleans.
[According to an eyewitness account from a pair of San Francisco paramedics who tried to leave the city], As they made their way to the bridge in order to leave the city "armed Gretna sheriffs (sic) formed a line across the foot of the bridge. Before we were close enough to speak, they began firing their weapons over our heads."
Members of the group nonetheless approached the police lines, and "questioned why we couldn't cross the bridge ... They responded that the West Bank was not going to become New Orleans and there would be no Superdomes in their City.
I agree with Kevin Drum: "Stuff like this makes me fear for the future of the human race."
We don't need attacks by foreign terrorists to destroy our society from the inside.
