I don't get the legal contradiction.
The search is supposed to be lawful without a warrant because you're not really in the US yet per-se, hence if you're not there, how deleting the data can be a felony?
The alleged crime is knowingly interfering with a lawful search (by providing a duress password that deleted the phone). Location has nothing to do with it.
right, there's a contradiction here:
- if you're deemed to be on US soil, constitutional protections (4A) apply; can't be destroying "evidence" unless you're accused of a crime or found to have committed a crime
- if you're deemed _not_ yet on US soil, then how can you be charged with a crime under _US_ law?
I think you legally are in the US while at an American border crossing - at least if the crossing is on US land, which it was in this case. It might be more complicated for preclearance spots. It's just that normal rights are suspended there despite being in the US, even for citizens. Make of that what you will.
