That's a misconception. Border/immigration agents can operate inside this zone, including making stops with reasonable suspicion or running checkpoints where everyone is stopped with no suspicion. The checkpoints are limited in scope, and do not provide authority for searching electronic devices. Some people, including a couple dissenting supreme court justices do feel the checkpoint part violates the constitution.
That's distinct from the border search exemption, which allows inspection of everyone and everything crossing the border. It only exists when someone is actually crossing the border and does not allow CBP to stop or search people who are not crossing the border.
Fun fact. Lack of parking is not a legitimate reason to attempt to drive past this region. I was once flagged crossing into canada on a day they were interviewing a lot of travelers. I spotted parking in what looked to me like an overflow lot on the other side of a fence, and when I slowly drove that direction sirens blasted and guns were drawn. Nothing gives you clarity like a gun pointed at you.
If there was a strip of land where you are not in a country then how can CBP assert any authority? No, you must be in America. There is no "no man's land," and there is no such thing as "international land" at America's borders where no law exists.
Seems like so far it didn't create any problems, so public is ok with that.
From Chief Justice Roberts in Riley v. California: "One of the most notable distinguishing features of modern cell phones is their immense storage capacity. Before cell phones, a search of a person was limited by physical realities and tended as a general matter to constitute only a narrow intrusion on privacy."
which is a good reminder for anyone with reason to be concerned about this sort of thing to turn off biometric/face id/etc. access to their devices.
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.
There is no reason for anyone to ever try to smuggle digital data through a border crossing and so zero justification for ever conducting a digital search at the border.
See for example https://www.jdsupra.com/legalnews/your-phone-can-be-searched...
no judge thought there was sufficient evidence to grant a warrant in this case, so what you're saying is that any CBP agent can go fishing for anything they want. anyone can be detained for any reason that an individual CBP agent considers necessary.
