Hasn't this been in effect since 2008? I have probably entered the US 100 times since then and have never had anyone show any interest in searching any of my devices, nor have I noticed them looking at anybody else's devices. Or did I miss something that is going to make them start doing this actively now? It is still scary as hell that this is possible at all, of course.
