Not quite that it's "no threat", more like no additional threat than memorizing a long passphrase and downloading / decrypting your illegal Canadian porno on the other side.

> Similarly, there is no possible way to harm an airplane based on what is present on a laptop; and even if there were, you could buy in-flight WiFi and download the bits after boarding. You could cross the checkpoint with a blank device and in seconds have it populated with whatever you wanted to have. It’s insane.

It's not insane though. The point isn't to catch anything, it's to acclimate the populace to this type of search and seizure. Kind of like how refusing to go through the body scanners at the airport earns you "What's up with that guy?" looks from other travelers.

It's not enough to just re-install the OS. You have to have your hardware recycled (discarded). Within a couple of seconds, they can put spyware onto your firmware by simply inserting a prepared USB device. The only way to get rid of that kind of spyware is to destroy the hardware.

The other solution is to not travel to any totalitarian countries or to travel there without any hardware, if you must.

You should not acknowledge, recognize or legitimise these 'unnatural rights'.

Even more important to me is the fact that once you lose exclusive physical control over your hardware, you must consider it compromised, and therefor have it recycled (it is enough to simply connect a prepared USB device to your device for a couple of seconds in order for you to lose total control over it and be under permanent and total remote surveillance).

To me, this is more than enough of a reason to simply not travel to countries like the US (and now apparently Canada as well) anymore. And any such country certainly doesn't deserve us.

At an extreme - if you had a document plan_to_takedown_flight_123ABC.pdf or diary_about_my_drug_smuggling_operation.txt, whether or not the data itself is a threat, it could indicate that you are.

I mean, I think it's bullshit, the same way I think most security screening and border guard questioning is bullshit, but if you wanted to maximize your border security (and keep out, ahem, "undesirables") and don't care about people's privacy, it's perfectly logical.

If your threat model is that someone capable enough to take down a flight is dumb enough to keep "plan_to_takedown_flight_123ABC.pdf" on their laptop, then it's logical. Otherwise you're wasting resources and _minimizing_ your security.
