The potential demand that visitors to the US hand over their social media records, or even their phones, opens up a world of embarrassment

As someone with a child in the US, this new Trump threat to scrutinise tourists’ social media is concerning. Providing my user name would be OK – the authorities would get sick of scrolling through chicken pics before they found anything critical of their Glorious Leader – but what if I have to hand over my phone at the border, as has happened to some travellers already? I would rather get deported.

There’s nothing criminal or egregiously immoral on there; I don’t foment revolution or indulge in Trump trolling, tempting as that would be. But my phone does not paint a flattering picture of me. Does anyone’s? Those shiny black rectangles have become contemporary confessionals, and we would like to believe they abide by the same kind of confidentiality rules.
