Kyanar:irongarment: 2) Nothing to hide nothing to fear. It seems that people don't want to post their Gmail passwords here. Why is that? You have nothing to hide right? The idea that you don't want to give your password to a random stranger but you will to a Customs officer seems odd. Unless of course in the entire history of humanity there has never been a bent official.What's your Gmail password got to do with anything? You're again banging on about an internet service account, which is both out of scope for this law, and outside Customs policy for device inspection. It's got nothing to do with this at all, apart from being a convenient strawman for you.
It's an example of something private, which someone might not wish to give to a Customs officer.
I realise it's out of scope because allegedly your device will only be searched locally, i.e. not connected to the internet, however most people will have the most recent chunk of Gmail messages stored on their phone which the official will be able to paw through. Naturally, if you have nothing to hide you have nothing to fear, so it's ok for someone to look at your recent email and attachments. Or the photos you have taken. Or your to-do list. Or the list of names and phone numbers in your phone book. Or your bank details.
Again, if you are not happy to post any of this on a public forum, then why would you accept someone collecting it at the airport?
