US Accuses American of Wiping Phone with Duress Password at Border

The U.S. Justice Department has taken an unprecedented step, prosecuting an American citizen for allegedly using a "duress" password to wipe his phone's contents during a border search. This marks the first known instance in the United States where federal prosecutors have brought charges for the alleged destruction of data via a device's built-in security feature.

Atlanta resident Samuel Tunick is fighting the charges, with his legal team asserting that the seizure of his phone by U.S. Customs and Border Protection (CBP) was unlawful. The case raises critical questions regarding an individual's constitutional rights when re-entering the United States, an area where the government has historically claimed expansive powers.

The Duress Password at the Center of the Case

The indictment against Tunick centers on a specific feature found in GrapheneOS, a customized Android operating system. This software, which Tunick's attorneys confirmed was running on his Google Pixel device, allows users to configure a secondary, "duress" passcode. When this particular passcode is entered instead of the primary unlock code, the device is designed to automatically and deliberately erase all its data.

The government's indictment accuses Tunick of providing border agents with a passcode that caused his phone to "delete the digital contents" before it could be fully inspected. Tunick has pleaded not guilty to the charges, which fall under a federal statute making it unlawful to knowingly destroy or damage property to prevent its seizure by authorities.

The Border Encounter and Legal Challenge

According to Tunick's attorneys, the incident occurred on January 24, 2025, as he returned to Atlanta's Hartsfield-Jackson airport from an overseas trip. CBP agents allegedly pulled him into a secondary inspection, where he was denied access to legal counsel and was not informed of his rights. His legal team claims agents demanded access to his phone under the pretext of searching for child exploitation imagery, but without presenting evidence to support this suspicion.

Tunick's motion to suppress evidence argues that the true motive behind the search was to investigate his involvement with Defend the Atlanta Forest, an environmental movement opposing the "Cop City" law enforcement training campus. The motion highlights the agents' assertion that a warrant was unnecessary because Tunick had not yet formally crossed the U.S. border, aligning with the government's long-standing position on warrantless device searches at ports of entry.

After Tunick provided a passcode, and agents entered it, his phone's screen reportedly went blank, flashed, and appeared to restart, indicating a data wipe. Despite the apparent erasure, authorities seized the device before allowing Tunick to enter the country.

Uncharted Legal Territory

Legal and security experts have noted the unprecedented nature of this prosecution. Matthew Dodge, an assistant federal public defender on Tunick's team, stated that the federal statute used for the indictment is rarely applied in such a manner. Bill Budington, a senior staff technologist at the Electronic Frontier Foundation (EFF), and Runa Sandvik, a digital security expert, both confirmed they had not encountered similar cases involving duress passwords.

Sandvik emphasized the implications for individuals with sensitive data. "I think this case serves as a reminder that authorities may argue you knowingly destroyed data, so it's better to not have that data on you when you cross certain borders," she advised, suggesting that individuals download necessary data after reaching their destination.

This case is poised to become a significant legal battle, potentially reshaping interpretations of digital privacy and constitutional protections at U.S. borders. The Atlanta federal court is expected to rule on Tunick's motion to suppress evidence later this year.

FAQ

Q: What is a "duress password"?

A: A duress password is a special passcode set up on a device that, when entered, automatically triggers an action like wiping all data, effectively making the device appear empty or factory reset. It's designed for situations where a user is compelled under duress to unlock their device.

Q: What are the constitutional rights at the U.S. border regarding electronic devices?

A: The U.S. government maintains it has broad authority to search and seize electronic devices at the border without a warrant or probable cause, arguing that individuals have reduced Fourth Amendment rights at ports of entry until they are officially admitted into the country. This stance is a subject of ongoing legal debate.

Q: What specific charge is Samuel Tunick facing?

A: Samuel Tunick is charged under a federal statute (18 U.S.C. 2232) that prohibits knowingly destroying or damaging property to prevent its lawful seizure by authorities. He has pleaded not guilty to this charge.
