Yep. There's this tendency to say "I beat their rules, so they have to let me go!" The CBP aren't fairies, they aren't bound to stay within some narrow precommitment. At least if you're not a US citizen, these things are almost totally discretionary. Not only can they bar you for not unlocking Facebook, they can bar your for genuinely not having Facebook if they decide you're lying. When even simple truth isn't a defense, clever tech tricks don't count for anything.

In my cynical moments, this outlook strikes me as a disease caused by excess programming - living in a world of contracts and invariants blinds people to how much of the world runs on "screw you, you know what I mean."

I think you are confusing TSA with CBP here.

Thanks, fixed that.
