Your link doesn't work, but you did show the URL so I checked it out anyway.
There is still no lie here. There was a set of Emergency Protocols in place for New Orleans and the state of Louisiana, both were prepared to do their part of the job. FEMA was also prepared to do it's part of the job. The problem was, the city and state officials didn't follow their own protocols. When FEMA came in, they were prepared for a disaster, but not to do the city and states job for them.
True, FEMA should have seen that happening and adapted to the reality of the situation. I don't for a second absolve FEMA for not doing so, since it wouldn't have required that much more than what is there job. However, they shouldn't have to.
The second that idiot Nagin decided not to follow "The New Orleans Comprehensive Emergency Plan", he started a chain reaction of failure. A chain that was only made worse when that moron Blanco made the equally disastrous decision to do the same with the state Emergency Management Protocols.
Any accusations that don't put Nagin and Blanco at the very center of what went wrong ARE just lies. Anyone who thinks that the President is the beginning and the end of an Emergency Response Plan is just plain ignorant.
