A US citizen, Sam Tunick, is being prosecuted for allegedly destroying evidence by wiping his phone, which was running the privacy-focused GrapheneOS, during an airport search. The case raises questions about the balance between security and privacy, as well as the limits of law enforcement's power at US borders. Tunick's phone wiped itself after he provided a passcode, and prosecutors argue that this was an intentional act to destroy evidence. The defense claims that the search was unconstitutional and that the evidence should be suppressed.
