It was the first post in this thread.
As for the rest, yes it is a bit unreasonable to assume a Federal authority should know exactly what's going on under a situation where even the local police don't have reliable communication.
Remember, if you can, that the meme that led to all this was that FEMA only found out about this when "everybody in the country" knew about it from the media the day before.
That turned out to be crap. So we've fallen back on the "they should have known anyway" meme. Go ahead and run with it.
