Ah, okay. Yes, inside the US it is pretty much the same. Borders are the exception and, I think, you need to actually be crossing in order for them to demand it

Ah, okay. Yes, inside the US it is pretty much the same. Borders are the exception and, I think, you need to actually be crossing in order for them to demand it. Citizens are immune, for the most part. Curiously, citizens aren't immune in Canada. I have dual citizenship and they still sometimes want to flip through my phone. No, I'm not sure why. They have had me power on and unlock my laptop a couple of times, as well.
