Well, yeah... the State would clearly prefer a "1984 approach".
We have always been at war with Oceania...
Not that I cross the border all that often.
Official: What is the password? Person: I don't know Official: Why wouldn't you know the password to your own laptop? Either you're lying, or you're definitely up to something nefarious.
Person: "I'm just a glorified delivery boy, they don't trust me with the company secrets."
However, in both these examples there is a very important difference. A thorough strip search would reveal that the person does not in fact have the required/desired keys.
Also, usually such people have superiors who may be contacted in order to get access (if they want to push it that far). I'm not sure if a person could use such a defence if they are a normal traveller or their company does not carry much weight.
There was a case - I don't recall the specifics - of a guy that was caught with child porn on his computer crossing the Canadian border. The courts compelled him to unlock his encrypted partitions because he had already unlocked them once (when asked to by the border agent) thereby proving that he had access to the keys. If he had never unlocked it in the first place, the fifth would have protected him against being compelled to decrypt the data, since the act of unlocking it would in effect be a coerced admission that the data was his.
I encrypt my stuff because if my laptop or phone or tablet is stolen or lost or rifled through, only bad things can come from it being accessible to the third party. It's possible that nothing bad would happen, but the options are "Nothing happens, minor bad things happen, major bad things happen." There is absolutely no upside whatsoever. I have company passwords, trade secrets, computer code, SSH keys, and other incredibly valuable things on my laptop. I have my own emails and email sessions, which provide unmitigated access to just about all of my online accounts. Failing to protect that means a huge downside risk with no upside whatsoever. Why wouldn't I?
When I travel, I don't carry the keys with me specifically for the same reason that I encrypt in the first place - in the best case, nothing changes, but in the worst case, being compelled to give up my keys could mean tremendous damage to my employer, my financial security, and my identity. I don't trust other people - especially people who have something to gain by my loss - to play nice or fair or right. It's simply a game of risk mitigation; it's not that I have anything particularly nefarious to hide, simply that I don't want to be able to be put into a position where I'm even able to allow my data to be owned by someone else.
It's the same reason why you use backups and exception handling - you hope for the best, but plan for the worst.
