Man sues feds after being detained for refusing to unlock his phone at airport
This is certainly not the first article of its kind, and the legality of such action seems to be upheld in court (at least the use of search without a warrant at the border).<p>So, the selfish question then is: How do I protect myself from such unwarranted searches?  Is there a way I can present my phone such that it drops into a mode that contains no data?  Do I need to back my phone up before traveling, wipe it for the border crossing, and then restore once I feel safe?<p>It feels crazy to ask this question, as an American citizen, but HN, what do you do to protect your data at the American border?
