“GrapheneOS provides users with the ability to set a duress PIN/Password that will irreversibly wipe the device once entered anywhere where the device credentials are requested.”
CBP demanded a passcode at Atlanta’s airport. Sam Tunick gave them one. The phone wiped itself, exactly as the software was built to do, and now he faces a federal charge under 18 U.S.C. § 2232. He never touched the device. The government’s position is that shipping a security feature and using it counts as destruction of evidence, which makes every GrapheneOS user a potential defendant the moment an agent asks.
