So each time I travel to Canada/Mexico, I have to leave my computer and tablet at home and spend an additional $50+ for a disposable phone that must remain free of all my personal data... You're proposing that as an acceptable solution to US law enforcement stealing my keychain and all my private data simply because they're standing a few feet outside US soil, which they claim entitles them to most certainly violate the intent of the US Constitution, which every customs officer has sworn an oath to defend? So NOT.
