For US citizens, encrypting your device, backing up with cloud storage, and accepting that your device may be seized if you don't provide passwords at the border sounds like the most usable (albeit imperfect) solution.

I'm not too concerned about my personal data at the moment. I interact with many non-citizens on a regular basis, and I am concerned that a misinterpreted Facebook message or email could land them in hot water.

It's not just ourselves we're protecting, but also our friends, family and colleagues.

At this point, spending $200 to get a burner laptop and dumb phone for international travel sounds like a really good investment - it doesn't seem to be worth the risk of taking your own hardware. Do you want TSA imaging your laptop (after you've unlocked it for them so they won't confiscate it) and putting whatever secret keys and embarrassing / private info is on there, into their own system, forever?

I travel frequently enough internationally that I need to bring my devices with me. If ICE (not TSA) asked me to log into my computer or phone, I would say no and accept the risk that they confiscate my encrypted devices.

The likelihood of ICE asking me to log into my devices and confiscating them is quite low. The inconvenience of using burner devices is quite high.

This of course assumes that the government is unwilling or unable to defeat your encryption.
