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transit through a U.S. port of entry while preserving the confidentiality of your most sensitive information, such as unpublished reporting materials or source contact information.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 Would be funny to take an old Pixel with a swollen battery and a half-popped display, install Graphene on it, then put no data on it, just encrypt it with a random number "password" so nobody can ever unlock it.

Take it to the airport and feed it to ICE. If you are lucky they will steal it and spend time in a futile effort to crack it. If you are REALLY lucky they won't notice that swollen battery, will try to charge it, and a battery fire in the "evidence room" will destroy more phones they are trying to crack.

It's just an old phone however unsafe, so this would be difficult to prosecute as phones with swollen batteries are not legally contraband.
