Device Encryption and Border Search: The Legal Line Is Still Unclear

A US citizen was charged after his GrapheneOS phone automatically wiped during an airport search. The thread went deep on VeraCrypt's hidden volume feature, the question of what crime was supposedly being investigated, and whether automatic device wiping can be construed as evidence destruction when there was no pending legal proceeding. The core legal tension: destruction of potential evidence requires a predicate, you can't go from zero to obstruction without an underlying crime.

GrapheneOS's wipe-on-failed-unlock is a feature, not a bug, and it is increasingly mainstream among security-conscious users. The charge implies prosecutors believe the intent was to destroy evidence of something specific, but the thread was skeptical about how that burden of proof gets met.

This is a canary. If this prosecution succeeds, it sets a precedent that using hardened mobile security configurations is itself legally risky when crossing a US border. That has direct implications for anyone traveling with sensitive business data, source code, or communications.
