Nope, no conspiracy there either. Just coincidence.
Some people are apparently so afraid of being perceived as tinfoil hatters that they deny the obvious right in front of their eyes.
I saw pictures of utter devastation in MS the day after the storm. Saw broadcasts from the reporters stationed in the motels above I-10, who had trouble getting down to the beach area the first day. Did you forget the phoned in report(couldn't use the satellite truck during the storm) from Jim Cantore's crew, where they had to move up to the 3rd floor of the VA hospital they were staying at, and had to help move the patients/residents up because of the storm surge? Forget Anderson Cooper's reports from the Waveland area, walking with a lady who was searching the slab area of her home for anything left? Forget the shots the next day of the casino boat on land at Gulfport? Forget the interview with the poor wandering man with 2 kids who told of how his wife was swept from his hands during the storm? A couple of days later NASA had before and after satellite pictures of the entire NOLA to Mobile coastal area. On the afternoon after the hit a Jackson, MS tv station had overhead video from Ocean Springs to Waveland, that was shown many times.
One can certainly argue that the media put more emphasis on NOLA than MS, but they sure as hell didn't ignore MS and AL. And given that for several days afterwards the destruction was over in MS, while floodwaters continued to rise and a massive evacuation (and hindering of such by the bungling LA state agencies) was ongoing in NOLA, it made sense that NOLA would get more coverage. The politicizing of it by much of the media is indeed disgusting and inexcusable, and probably did slant the coverage to NOLA, but it didn't stop the coverage of MS and AL.
