Thanks for the link. I wrote "could be" instead of "are" because I have no proof they "are" right now. My point was that the powers that be don't have a clue.
I have predicted before that if, God forbid, the US is attacked with a nuclear or biological weapon, it's entry will be traced to our Southern border.
Then, maybe, Janet, et al will get their heads out of their asses and get serious about the Southern threat.
