For people who are concerned about having their devices seized at US airports starting Monday when ICE "assists" the TSA, EFF has this guide: https://www.eff.org/deeplinks/2025/06/journalist-security-checklist-preparing-devices-travel-through-us-border
A Journalist Security Checklist: Preparing Devices for Travel Through a US Border

We wrote this checklist to help journalists prepare for transit through a U.S. port of entry while preserving the confidentiality of your most sensitive information, such as unpublished reporting materials or source contact information. It’s important to think about your strategy in advance, and begin planning which options in this checklist make sense for you.

@evacide one flaw in the guidance is it assumes there is still the rule of law in the US, e.g. the difference between US citizens and not. Minneapolis has shown otherwise.

If I were a journalist or any other enemy of the gangster state, I'd basically rely on Tails OS on a flash drive purchased locally, with all information stored on encrypted storage overseas. Also to be prepared for rubber-hose cryptanalysis.
