FEMA said in a followup email that the message was sent out mistakenly.
Their statement below reads:
Somebody at the Federal Emergency Management Agency is a Saints fan.
There’s no way this gets sent out by accident.

If it simply declaring a disaster in a specific area, or suburb of Dallas.
Even if it were declaring an emergency is Arlington.
Then I would think it was simply a mistake.

Somebody must have fat fingered the, “Declare Emergency in Dallas” button.
I mean, come on.
I also love the, “In the areas affected by the New Orleans Saints”.

But I think someone was trying to have a goof.
It must have been a slow day of emergencies on Sunday.
I guess there was that one Presidential assassination attempt.
But that was in Florida.
The Dallas office must have been bored.
He probably called over of few of his Cowboy fan co-workers to bust balls.
“Hey guys would you mind proof reading this for me?”
Then had a good chuckle at their expense.
You think that’s funny?
“, then reached over his shoulder and sent it out from the Saints fan’s computer.
Good luck explaining that one, pal.
Or maybe someone at FEMA just has a good sense of humor.
Exercising your humor in the form of a real news declaring a disaster happened.
But if you ask me, that’s just good clean humor.
very hilarious message to send to the Dallas media following a Cowboys beatdown.
That’s basically all their job is nowadays after all.
