Border insecurity: Your laptop, please
Last month a US court ruled that border agents can search your laptop, or any other electronic device, when you're entering the country. They can take your computer and download its entire contents, or keep it for several days. Customs and Border patrol has not published any rules regarding this practice...
But the US is not alone. British customs agents search laptops for pornography. And there are reports on the internet of this sort of thing happening at other borders, too. You might not like it, but it's a fact. So how do you protect yourself?
The short version: "Delete everything you don't absolutely need."
