I think they probably know where, it’s the when of the equation in question. Most likely the “refugees” go through DHS centers first. DHS has set up facilities to house/process illegal immigrants before transferring them. My county has supplied the site for one of them, everyone connected to government knows where the facilities are located.

I think you are overestimating the information that gets disseminated to the states/locals.
This whole new era of information sharing most often only goes one way, up.
Inter-agency cooperation is still laughable, and when DHS is involved, most often “you don’t need to know”.

I can believe Jindal didn’t know, odds are he’s out of the loop on many things the Feds do down there. As are we all.
