When I recently reentered the country this year there literally was no security process other than scanning my face and my passport at an automated thing. After that, it was just walk on through. No talking with any agents, no search of my carry on bags (at least until going through TSA to fly domestically).
I think people’s checked baggage was heavily scrutinized and scanned, but not any carry on. It was honestly kind of crazy. Like what if I had come from a country with virtually no exit security, and then was not flying domestically after that? I feel it would have been quite easy to smuggle things into the country in that case. Meanwhile they occasionally freak out and force people to let them search their phone? It makes little sense to me
