A landmark legal battle is unfolding in the United States, where a citizen stands accused of intentionally destroying data on his mobile phone using a 'duress' password during a border inspection. Samuel Tunick, an Atlanta resident, is fighting charges brought by the US Justice Department, marking what is believed to be the first federal prosecution of its kind involving such a software feature.
According to court documents and media reports, Mr Tunick allegedly provided a passcode to US Customs and Border Protection (CBP) agents that caused his phone to wipe its digital contents. This action reportedly took place as he returned to the US through Atlanta’s Hartsfield-Jackson airport on 24 January 2025, following an overseas trip. The indictment against Mr Tunick stems from a federal statute prohibiting the knowing destruction or damage of property to prevent its seizure by authorities.
Mr Tunick's legal team has filed a motion to suppress all evidence, arguing that his detention and the seizure of his phone were unlawful. They claim that during the secondary inspection, Mr Tunick was repeatedly denied access to legal counsel and not informed of his rights. His attorneys also assert that CBP agents demanded access to his device under the pretext of searching for child exploitation imagery, but without presenting evidence to justify such suspicion. Instead, they contend the government was investigating Mr Tunick over his alleged association with an environmental movement known as Defend the Atlanta Forest, which opposes a police training facility project.
The case centres on a specific feature within GrapheneOS, a custom Android operating system confirmed to be running on Mr Tunick's Google Pixel device. GrapheneOS allows users to set a secondary passcode that, when entered, deliberately wipes the device’s data instead of unlocking it. Security experts and legal observers have noted the rarity of such charges, with none recalling a similar prosecution involving a duress password feature.
This prosecution reignites significant debate over the scope of constitutional rights at US borders. The US government has historically maintained that individuals have fewer constitutional protections at the border, asserting broad authority to search and seize devices without a warrant or court order before a person is formally permitted entry into the country. Mr Tunick's legal challenge directly confronts this long-standing governmental position, potentially setting a precedent for digital privacy rights for travellers entering the US.
