Gosh, you are dense, aren't you?
The President of the United States did that, not FEMA.
And he did it so he could order FEMA to PRE-POSITION resources before the storm.
Name calling. How mature. If it was pre-positioned as you say, why did they not disperse it after the storm hit? Why did it take days?
Re: declaration of emergency and disaster - the locals are still driving the buggy. Local/state officials first make a local declaration, then request federal designation as same. E.g., Blanco declares "State of Emergency" in Louisisna, and asks the President, through FEMA, to make a parallel Federal declaration. That protocol was followed in this case.
