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transit through a U.S. port of entry while preserving the confidentiality of your most sensitive information, such as unpublished reporting materials or source contact information.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 Thanks for the timely reminder. I strongly support the work of #EFF . Everyone who has demonstrated or even expressed as little as a sentiment contrary to the regime should be concerned about what could happen when you in a border zone or crossing a border into or out of the US. If you are or become a “person of interest” then you must take personal #infosec seriously. I will never take the device I’m typing on right now across a border. Nor my personal smartphone.
