I cross borders many times a year. I am "randomly selected for a in-depth search" 1 of every 3. Welcome to my world.
But they don't check the content of your disk?
Those are still high numbers!

Perhaps, I have a quite boring life but I know for a fact that there is someone in Mexico with a similar name that is on a list. My electronics devices are not searched, although I have been asked to turn them one of them once in a control.
