The US Department of Justice is prosecuting Atlanta resident Sam Tunick for destroying potential evidence on his phone, in a case that tests how a federal property-destruction statute applies to privacy-focused software. Tunick's first hearing took place on July 20, 2026, and details of the government's investigative methods were reported by The Guardian on July 23, 2026 The Guardian.

The case, docketed as United States v. Tunick (1:25-cr-00499) in the US District Court for the Northern District of Georgia, stems from an incident at Atlanta's Hartsfield-Jackson airport on January 24, 2025. Tunick was stopped for interrogation after returning from a vacation in the Dominican Republic. Federal authorities had placed him on a terrorism watchlist due to his alleged association with the movement against the Atlanta police training center known as Cop City The Guardian.

Three hours before Tunick's arrival, a homeland security agent circulated an email containing his name and photograph to the Customs and Border Patrol tactical terrorism response team and an FBI Atlanta joint-terrorism taskforce officer. The email indicated Tunick was being investigated for 'suspected terrorism activities,' according to courtroom testimony. During the secondary inspection, agents questioned Tunick about child sexual abuse images. His public defenders described this line of questioning as a pretext for a fishing expedition into his Cop City connections The Guardian.

The prosecution centers on Tunick's phone, which ran GrapheneOS, an open-source operating system available on Google Pixel devices. GrapheneOS is designed to enhance privacy and security; one of its features lets users enter a specific passcode that instantly wipes the phone's contents. Tunick provided a passcode to agents, which resulted in the erasure of the phone's data. The DOJ is prosecuting Tunick under 18 USC § 2232, a statute that makes it a crime to destroy property in an effort to prevent it from being seized The Guardian.

Tunick was arrested in Atlanta on December 2, 2025, following an indictment signed by Magistrate Judge Regina D Cannon on November 13, 2025, which was accompanied by an arrest warrant. He entered a plea of not guilty Atlanta Press Collective. Tunick's federal public defenders filed a motion to suppress all evidence agents obtained, including the phone erasure, citing alleged violations of his constitutional rights. According to courtroom testimony, Tunick asked four times during the interrogation to speak with a lawyer and was rebuffed each time The Guardian.

The Tunick case is the second recent federal effort against Cop City protesters, following another DOJ indictment announced in June 2026. The Cop City police training center, which cost $109 million, opened in spring 2026. Several state attempts to prosecute Cop City protesters have foundered over the last several years The Guardian.

The application of 18 USC § 2232 to the wiping of a digital device raises questions about how courts will treat privacy-focused software under property-destruction statutes. Christophe Boutry, a cybersecurity and surveillance expert, said the case is concerning and sends the message that 'GrapheneOS is criminal by default.' Bill Buddington, senior staff technologist at the Electronic Frontier Foundation, said he had not seen a similar case The Guardian.

The case also draws attention to the use of watchlist-based secondary inspections at points of entry as an investigative tool for domestic political movements. The testimony that Tunick was questioned about child sexual abuse imagery during an investigation focused on environmental and police-accountability activism, and that he was denied counsel four times, provides the factual basis for the defense's suppression motion. The outcome of that motion will determine what evidence is admissible as the case proceeds.

The broader context here is a collision between decades-old property law and modern privacy technology. The statute at issue, 18 USC § 2232, was written with physical objects in mind — documents dumped in a river, a hard drive smashed with a hammer. Applying it to a software feature that erases data by design asks courts to decide whether entering a passcode constitutes the same kind of intentional destruction as burning a ledger. If the prosecution succeeds, it could reshape how law enforcement treats encrypted or privacy-hardened devices, and potentially discourage people from using tools designed to protect personal data.
