double win: it could put to "work" the hoards of unemployed, recent JD grads. Nice try border-guard, but I can't unlock this smartphone because my attorney is "reviewing" my European vacation photos.
Well this actually is interesting. Is a third party expected to respect atty client privilege if that third party is used for storage? Surely not. Also, could a law be passed that states some storage (like phones) is from the factory not protected by atty client privilege, like a usb drive? Could an atty be made aware of the contents of storage even though the storage is not in attys possession? What if atty just has cred access to the storage? That enough? Man, if any of that could be enforced, it would cause all kinds of chaos for LE.
The authorities aren't allowed to get the information from your attorney, that has nothing at all to do with asking you to give that information yourself.
