ATLANTA, Georgia — An American activist has been charged with a federal offence after authorities alleged he intentionally erased the contents of his mobile phone during a search by U.S. Customs and Border Protection (CBP) officers at an airport, in what legal experts describe as an unprecedented case that could shape the future of digital privacy rights at U.S. borders.
The accused, Samuel Tunick, was stopped by CBP officers upon returning to the United States through Hartsfield-Jackson Atlanta International Airport. Federal prosecutors allege that during questioning, Tunick entered a special security passcode on his phone that automatically erased all of the device's data before investigators could examine it.
According to court filings, the phone was running GrapheneOS, a privacy-focused operating system that includes an optional "duress password" feature. Unlike a normal passcode that unlocks the device, the duress password is designed to immediately wipe stored data if entered, allowing users to protect sensitive information under coercive circumstances. Prosecutors claim Tunick deliberately activated this feature during the airport inspection.
Federal authorities have charged Tunick with destruction of evidence, arguing that he intentionally prevented investigators from accessing potential evidence during a lawful border inspection. If convicted, the case could establish an important legal precedent regarding whether deliberately deleting digital information during an official search constitutes a criminal offence.
Tunick's lawyers have strongly rejected the allegations, arguing that the airport search itself was unconstitutional. They contend that border agents used allegations involving child sexual abuse material as a pretext to investigate Tunick's connections to the "Stop Cop City" protest movement in Atlanta, rather than conducting a legitimate customs or immigration inspection.
The defence also argues that Tunick repeatedly requested to speak with a lawyer before providing access to his phone but was informed by officers that they did not need a warrant to examine the device. His attorneys are seeking to have the evidence dismissed, claiming the search violated constitutional protections against unreasonable searches and seizures.
The case has attracted significant attention from civil liberties organizations, cybersecurity experts, and privacy advocates. Groups including the American Civil Liberties Union (ACLU) argue that the legal rules governing electronic device searches at U.S. borders remain inconsistent, with different federal courts reaching different conclusions about when warrants are required.
Legal experts note that U.S. border authorities possess broader search powers than police operating inside the country. However, courts have not reached a uniform position on the extent of those powers when it comes to smartphones and other digital devices, particularly because they contain vast amounts of personal information.
Privacy advocates say the outcome of the case could influence future treatment of encrypted phones and privacy-focused software. They caution that using security or encryption tools is not, by itself, evidence of criminal activity, but acknowledge that intentionally deleting data during an active government search raises complex legal questions.
As the case moves through the U.S. federal court system, it is expected to become a closely watched test of the balance between national security, border enforcement powers, digital privacy, and constitutional rights in the age of encrypted technology. A final ruling could have significant implications for travellers, privacy software users, and future border search practices across the United States.
