The scary part is that this represents an attempt by the Executive branch to appropriate the right to detain anyone regardless of what the Judicial branch says.
Sadly, I think previous administrations already did their best to erode judicial protections, with the secret watch lists, etc. Not to mention sending people to other countries to be "interrogated" (AKA tortured) outside US law. But Trump has certainly taken things to new heights. Apparently, he didn't even bother having Department of Justice vet the executive order first. And when CBP is actually defying court orders, something has gone very wrong indeed. Still, I've never seen the judicial branch react this fast to counteract an executive order, across multiple states. I'm hoping that some airports will soon be seeing contempt of court orders.
btw, I've even heard rumors of student visas being revoked for no reason, a week before the order was even signed.
Personally, though, I'm finding the changes to the Principals Committee the scariest. Just because it's such an obvious statement of who holds the influence in this administration - they're not even trying to hide it any more.
A small silver lining: Trump has apparently reached majority disapproval in record time - 8 days. It took Clinton, the previous record holder, 573 days.
