It was a bad idea, because I think that any government reorganization has to come in relatively small bites, or else you get indigestion.
If there were a major earthquake in Los Angeles, with bridges and highways and railroads and airports all shut down and huge buildings collapsing, I don't care how much planning you do, the first 72 hours is going to be chaotic.
The other thing about FEMA, my understanding is that it was supposed to move into the Department of Homeland Security... and be what it was, but also having a lot of lateral communication with all those others involved in that issue of homeland security.
