This is has been going on for DECADES. Also, I think you intended to say "border crossing". Thats a very important detail as INTERNATIONAL AIRPORTS ARE BORDER CROSSINGS.
Most of the US population lives within 100 miles of a international airport or other international border crossing. Yeah, most people don't know that....
Also, I have a "Travel device" that is fully wiped/reflashed/factory reset every single time I travel (before travel then again after travel). I have HDD's I swap out of my laptop that are also wiped and a fresh OS installed with zero saved ANYTHING. I don't need to travel with "pre configured" systems (the only exception being a work device but fuck that, they can have my work devices I don't own them or use them for personal shit).
People call me paranoid. I say they are not paying attention.
I once was entering. I had done a fuck load of Timelapse photography.
The niggers cracked the netbook open and were like what dis be. I said timelapse photography. Wut? Push the down arrow and watch the 1000’s of photos scroll by.
Wow like motion pictures for parent apes for the first time.
In reality I could have stenographed all the secretes in the world in those 10,000+ images…
I do the same. I keep waiting for them to say “where’s your iPhone” What iPhone I have this nexus 5x bro. Wiped. Nothing on it but my federal attorney's number.
Get fucked cunt.
This is the way. OpSec should be on the list for home-schooling if you have kids.
