That is what I was wondering too, but clearly the gangsters that have taken over New Orleans have to go and quickly. One thing for sure, Delta is not there to do police work, they are there to take ground away from bad guys.
I'm pretty sure that there is a number of former Delta/Marine Recon etc. that would be interested in dusting off old skills. Or maybe there's a clause to PC that I don't know of.
At any rate, I think SFOD-D would be a little busy around the world to handle this. I bet that a platoon of staright-leg Louisiana NG infantry could take care of this.
