Just gonna leave this here. This is the America xenophobes have voted for. Total incompetent Police State where you get threatened, detained, and potentially your property destroyed because you actually exercise your rights:
Your paranoia and distaste for "the other" has gotten us here, where the enforcement officers dont know or care about laws, or the Constitution itself. But we already know you dont care about the Constitution, either so long as people you don't like are being ill-treated. And the best part about it is the CBP Cop admits they just want to be told what they want to hear from this particular guy. That if he just said a single word, which he doesnt have to under the 5th Amendment, they would have just let him go, which demonstrated that these inspections are a joke, or it would have only been different had he looked or sounded different.
