This story had been picked up by more overseas newspapers than U.S. papers. Here's some links to more stories on this matter:
Houston Chronicle:
http://www.chron.com/cs/CDA/ssistory.mpl/nation/3357471"Gretna is not the only community that views New Orleans with distrust. Authorities in St. Bernard Parish, to the south, stacked cars to seal the roads from the Crescent City into their parish. But Gretna officials have been deluged with angry e-mail messages, accusing them of racism."

"We were fighting for our lives to save people, and every decision we made was based upon trying to move people to safety," Nagin said. "When we allowed people to cross the Crescent City Connection because people were dying in the convention center, that was a decision based upon people." Gretna, he said, "made a decision to protect property."

Seattle Times - discusses MSM coverage of the story
http://seattletimes.nwsource.com/html/nationworld/2002498314_bridge16.html"Almost in unison, newspaper editors across the country pooh-poohed the news value of cops firing toward black people on a bridge in the Deep South. In the days following its publication in the Socialist Worker, the drama clambered onto the pages of the San Francisco Chronicle and the Houston Chronicle in addition to scoring a brief on UPI. The relative silence proved a maxim of print journalism: It's painful to credit other journalists, and it's really painful to credit a pair of part-time socialist journalists.
...The Times didn't showcase the story — it landed on A13 of a Saturday edition. "I think the story was important enough that we don't have to be first all the time," says Harris. Slonsky says the Los Angeles Times almost made the same judgment but declined to run a piece at the time. The Los Angeles Times refused to comment.
The Wall Street Journal passed on the bridge story, too. "When we decide we want to go along, we go along. We kill a lot of stories each day because we're judicious about what we put in the paper," says a Journal editor. Says ABC's Donvan: "I was very surprised more people didn't go for it."
