Is it illegal to trick the US government into wiping your phone during a questionably legal search?

Tunick’s case has some details in common with the one that precipitated the New York ruling. The New York case began with a criminal investigation of Kurbonali Sultanov, a naturalized citizen from Uzbekistan whose name triggered an alert on the Treasury Enforcement Communications System, which identified him as a potential purchaser of child sexual abuse material. In court, Sultanov said agents told him he had no choice but to unlock his phone. He was also questioned by agents with ICE’s Homeland Security Investigations, who read Sultanov his Miranda rights, which he said he understood “50/50,” before questioning him.

It’s unclear why CBP agents believed Tunick had child sexual abuse material on his phone. The two-page indictment filed in a Georgia federal court makes no mention of it, and CBP did not respond to The Verge ’s request for comment.

“Under the Fourth Amendment, a warrant should be required, or at a bare minimum, specific suspicion that there is illegal digital contraband on the device,” Nathan Freed Wessler, the deputy director of ACLU’s Speech, Privacy, and Technology Project, told The Verge. “Agents should never be allowed to conduct warrantless searches on behalf of domestic law enforcement agents who just want to evade the normal Fourth Amendment requirement to get a warrant from a judge.”

The suspicion that immigration agents are surveilling activists has plenty of basis. In a lawsuit filed in Minnesota federal court , a Minneapolis labor organizer claimed that CBP was conducting “systematic” searches of activists’ devices, using counterterrorism as a pretext to keep tabs on the president’s left-wing critics. In March, more than a dozen members of a convoy that delivered humanitarian aid to Cuba had their phones seized at Miami International Airport.

Phone inspections at ports of entry are still relatively rare: CBP searched 55,318 phones and other electronic devices during the 2025 fiscal year, a 32 percent increase since 2023. (The US had more than 5 million international visitors in June 2025 alone, a figure that doesn’t include US residents.) But activists across the country have noted an uptick in surveillance since Trump returned to office, and the president has focused on cracking down on the left during his second term.

Last September, Trump issued an executive order designating “Antifa” as a domestic terrorist organization , even though there is no single organized entity known as antifa. In June a federal judge in Texas sentenced eight activists to upwards of 30 years in prison for supposedly belonging to an “Antifa cell.” The State Department recently issued a 100-page report alleging that several left-wing groups, including the Democratic Socialists of America, CODEPINK, and others were “front groups and fellow travelers” of the Cuban government. The report claimed that Cuba had influenced social movements in the US, including the 2020 Black Lives Matter protests, and tied the Standing Rock and Cop City protests to “Antifa.”

As Trump’s crackdown on the left continues, activists who travel internationally may find themselves under additional scrutiny at airports and other ports of entry. Though US citizens can’t be barred from entering the country, CBP can seize their devices and attempt to break into them with advanced forensic tools. To prevent federal agents from accessing the contents of your phone, privacy experts suggest backing up and wiping your device — before traveling, not during an interrogation.

William Budington, a senior staff technologist at the Electronic Frontier Foundation, explained that “a judge is not likely to view the use of a duress password sympathetically.” The EFF cautions against erasing the contents of your device mid-questioning, as Tunick is alleged to have done. “Factory resetting your device in your personal time is well within your rights.”
