The Cover-up has begun...
Not really begun, as much as continues. As noted previously, the City of New Orleans posted an official emergency plan on its website: http://www.cityofno.com/portal.aspx?portal=46&tabid=26.
Fortunately, knowing this might happen, I saved the relevant portion:
Conduct of an actual evacuation will be the responsibility of the mayor of New Orleans. ...The city of New Orleans will utilize all available resources to quickly and safely evacuate threatened areas. ...Special arrangements will be made to evacuate persons unable to transport themselves or who require specific life-saving assistance. Additional personnel will be recruited to assist in evacuation procedure as needed. ...Approximately 100,000 citizens of New Orleans do not have means of personal transportation.This link worked not just a couple of days ago, however, now it appears I do not have sufficient access to view the plan. Or, perhaps, it's down for maintenance and retooling to fit circumstances.
Or they're just plain embarrassed.
