As if the security in airports and controls at border crossings weren't slow and intrusive enough, governments around the world are quietly passing laws to allow them to search the contents of your laptop and other electronic devices, like iPods and cellphones. A United States court last month gave border agents carte blanche to hold a laptop for days and even copy its entire contents. The UK government has given its agents authority to search computers at its borders for pornography. But in what may be the most baffling and cumbersome move of all, the US, Canada, UK, and other EU nations are working behind closed doors on a new trade agreement which could turn border agents into the copyright police.
