They’re there because you’re being watched already. You’re coming in from an international flight to the 11th district so they have unreasonable search and seizure rules.

Graphine is clean enough that they can’t sidestep it. Just plead the 5th and leave it at that. They’ll probably confiscate it in hopes they’ll eventually be able to break it on a zero day.

Telling them the duress password is the unlock code will def get you fucked.

Pleading the 5th and then them entering a password found in your wallet that wipes it will get you dragged into court, but probably in a defensible position; those lawyer fees are going to be immense.

Pleading the 5th and having your duress as 1234, which they try, would also put you in a defensible position with 10s of thousands in lawyers’ fees.

The duress password isn’t illegal. The knowing destruction of data is. If you set it up so they’re likely to destroy the data in attempting, you’re going to get served.

Don’t go through a border with a phone full of questionable personal data. Legal or not.
