The US government is prosecuting American citizen Sam Tunick for allegedly using a 'duress password' to wipe his phone when federal agents tried to seize it at Atlanta's Hartsfield-Jackson airport on January 24th, 2025. The case, which hinges on a rarely-used statute against destroying property to prevent seizure, centers on Tunick's use of a feature in the privacy-focused Android operating system GrapheneOS.

According to court filings, agents detained Tunick and questioned him about child exploitation images—a claim his lawyers call "a pretext for a fishing expedition" into his ties to the Stop Cop City movement. Tunick's attorneys argue the detention and seizure were unlawful, noting agents refused him access to a lawyer, did not provide a warrant, and failed to inform him of his rights. The government counters that a warrant was unnecessary because Tunick had not formally entered the US.

The case tests the boundaries of digital privacy at borders, where courts have historically granted authorities broad latitude. GrapheneOS's duress password feature—designed to allow users to unlock a decoy profile or wipe the device under coercion—is legal software, but using it to thwart seizure may invite legal liability. As Marlon Kautz of the Atlanta Solidarity Fund told The Guardian, "We all have a right to secure our private data against unconstitutional searches."

For developers and privacy-conscious users, the prosecution sends a chilling signal: even citizens exercising technical self-defense at the border may face criminal charges. With the Trump administration intensifying scrutiny of travelers' devices, the only reliable protection may be to carry no data at all—an increasingly untenable position.
