These days, Canadian immigration authorities are
attempting to search the contents of all laptops entering the country for pornography (at least that stored in really obvious places):
But he is stuck. There is nothing familiar. So he clicks on the start menu and finds "My Pictures". You know, if I was into that - that is precisely where I would stick all of my porn - right there in "My Pictures". He goes into it - and sees all of my folders. And al of my pictures, which we looked at. He said "wow, you travel a lot", I said "yup".
Now, after about 15 minutes of looking at my pictures (I have to resist the urge to point him to my favorites :) he shuts down my computer and says "Ok sir, thank you very much, have a nice trip".
And in the comments:
At the US border they are allowed now to seize your laptop and search for porn. Then your laptop will be returned at some other time if nothing is found. Some people have not had their laptop returned after almost a year.
Recently, US transport regulations have mandated that all luggage checked at an airport be unlocked or else be locked with a special approved padlock that can be opened with a master key by the authorities. Perhaps in a few years' time, they will mandate that all laptops have a means by which the entire contents can be copied at the airport, for external scanning for pornographic/terrorist/copyright-violating content.
