Honestly, neither does having to securely wipe SD card (or any storage device for that matter) as one cross the international border like the thread further up suggests. So the whole thing is just having fun with (potentially roleplaying) over paranoid people :)

These SD cards are for photographers and normal expandable storage for devices and not state secrets or something highly illegal.
