A question for Real Lawyers on the circuit split on the border search exception for digital device searches (https://www.findlaw.com/legalblogs/law-and-life/cbp-border-phone-searches-face-patchwork-of-rules-for-returning-u-s-citizens/): what circuit’s rules control what can be done in a border search outside the physical boundaries of the country, e.g., at a Canadian airport?
@SteveBellovin IANAL, but it's not a question that's occurred to me. And I have a very thick tin-foil-hat, so that's embarrassing.
I pretty much stopped flying when TSA was invented (except for work), and resolved to never take electronics with me if I cross a border.
Since the SCOTUS ruled that I have no Constitutional rights withing 500 miles of any border, especially the 4A rights, I keep nothing of value on my phone anyway, since it's always at risk.
