So now those school buses were FEMA's responsibility?

From Guards' Katrina response questioned we learn that:

One of the key leaders of the state's response to Hurricane Katrina came under fire from [Louisiana] state lawmakers Tuesday, including how long it took the Louisiana National Guard and others to reach disaster areas.

The chief target of the grilling was state Adjutant General Bennett Landreneau, who is responsible for deploying the 14,000 members of the Louisiana Army and Air National Guard. He also is director of the Louisiana Office of Homeland Security and Emergency Preparedness...

Hmmm? Landreneau as 'director of the Louisiana Office of Homeland Security and Emergency Preparedness' was responsible for keeping Lousisana's end of the The Federal/State of Louisiana emergency response agreement which notes:

1. To the maximum extent possible, internal State and local resources should be used as the first line of support in response to a disaster. Intra-State and inter-State mutual aid can provide an additional option for timely and cost-effective resource support that can be executed prior to a Presidential disaster declaration.

Which is why the following is surprising coming from General Landreneau:

...Landreneau said his two key regrets are that school buses overseen by the Federal Emergency Management Agency did not arrive sooner to help evacuees leave New Orleans and crippling communication problems...

(Sarcasm alert)
Uh...come again?!? Is he talking about these school buses?:
