Of course not. Your organization could not effectively function with that type of direct honesty. Do not, however, expect any response from those of us who've educated ourselves re: our rights in such an encounter.
At ROC, couple of weeks back, observed CBP officers, one on each side of travel check, apparently waiting for non-US passports to be proferred for TDC "papers, please" processing. The CBP officers would then spring over to the TDC podium, and get involved in the processing, presumably looking for further proof of legality to be in the country. The hypothetical individual legality of presence challenge in TX is already happening continually in upstate NY.
I also tried a non-US passport at TDC but could generate no such challenge.
Perhaps they know me from FT.
How much further does this need to go before all can see that our airports have simply become an internal border?
(BTW, it's always easy to know when CBP is piling on to the airport check-point Charlie, they need at least 2 vehicles, miraculously exempted from the FAA no stopping directives, highly visible, parked in the ROC airport tow-away zones.)
