unless the phone itself is a suspicious good, there should never be any justification for a border officer to demand visibility of the contents of the phone, or the data that its permitted to access on other systems.
I presume the counter to this is that they must be able to examine the socials in order to see if you should 'death to america' on message boards. is that really an important vector? is the balance of that security concern versus speech rights (which are supposed to be 'universal') something we want individual field officers to decide?
Personally, I believe that there should be explicit laws protecting your personal devices, given the amount of sensitive private information they carry. I think an explicit law, or even amendment to the constitution, would be much better than relying on ever more arcane legal interpretations being invented by judges based on vague wording and vague principles.
