The issues arise with the fact that every countries border is inherently leaky anyway: the internet makes sure of that. So, searching your computer and confiscating your device because you're not a fan of some not-even-a-cop going through your stuff will just push those that they want to catch to transferring files somewhere to retrieve when they're in the country.
I'm an Aussie. I have nothing to hide in terms of data on my computer, as far as I know. If I was flying to USA (as an example) tomorrow, I'd wipe my laptop and phone clean, put images on my server, and access them via SSH once I'm through the border... Why the hell do I need to do that?
Given the way US allies behave, I'm not sure your data is any more safe at home. New Zealander here. Amusingly, I know of several people here who cc our prime minister every time they send an email, to save him the effort of signing any request to spy on a citizen. His mailbox must be something awful.
