Well, here you go. Ray Nagin: School Buses Not Good Enough.
It seems that school buses weren’t good enough for the people of New Orleans. Mayor Nagin wanted to get these people out of there via Greyhound-type liners.
Here it is, straight form his own mouth:

“I need 500 buses, man,” he told [radio station] WWL. “One of the briefings we had they were talking about getting, you know, public school bus drivers to come down here and bus people out of here.”
“I’m like – you’ve got to be kidding me. This is a natural disaster. Get every doggone Greyhound bus line in the country and get their asses moving to New Orleans.”

This really is two disasters rolled into one. First, you have the natural disaster that was Katrina, then you have the man-made disaster that was Blanco and Nagin. Their incompetence and arrogance cost how many hundreds, even thousands of lives we’ll never know.
