As I read this article I remembered the article published in The Register *just last week* which reviewed the should's and should not's with respect to data security when travelling to the US. It was clear in the article that demanding passwords is not a new thing. That TSA staff have been able to require access to phones for years and, if password to social and other accounts are on the phone then their contents are fair game. And if you do not offer up your phone then staff are within their rights to confiscate the device and send it away for forensic investigation.
Since this is not a new thing or even a new practice why is a fuss being kicked up now. I have no love for President Trump but I have even less love self-serving hypocrisy. This hypocrisy feeds Trump's narrative of fake news when this 'news' should have been brought to light while Barry was in charge.
