I've heard plenty of other moments when FEMA prevented rescuers from
rescuing. I suspect they are the "Department of NO".

The recent Shingles Creek fire in Utah consumed nearly 10,000 acres.
Authorities said that it could have been much less than that if the
bulldozers could have worked more on the first day. It was estimated that
the fire would have burned only 1,000 acres. But, they had a federal
guideline, and had to stop at 4 or 5 PM, according to the rules. By the
next day, the fire was full on.
