Straight from the Electronic Frontier Foundations website :

“On April 21st, the Ninth Circuit held in United States v. Arnold
that the Fourth Amendment does not require government agents to have
reasonable suspicion before searching laptops or other digital devices
at the border, including international airports.”

This is very bad. If you know someone who’s got a laptop, then you know that theres a lot of personal stuff on it. There can be family photos, emails, notes, personal finance data, and other things that you just don’t want other people seeing. You don’t let other people read your diary, so why should you let other people read the contents of your laptop? (The ruling doesn’t apply just to laptops by the way – its ANY electronic devices, so it could include your cell phone, the photos on it of you and your friends who may or may not have drunk too much last week, the business calendar of meetings on your PDA, etc.)

Other then an invasion of privacy, I don’t see any need or benenfit to allowing border agents to search laptops. This isn’t the 1800s where to get sensitive information into the US, it had to be carried in paper form, contained inside a locked box. There’s email, websites, downloads, and loads of other ways to get data over the border. Searching laptops should not be allowed without reasonable suspicion.

On a less serious note, if I have a logon that requires a password, and I don’t give you that password, does that count as copy protection for my laptop, therefore meaning that if border agents try and get around my password (without me giving it to them – they can’t search my brain without reasonable cause) they are guilty of violating the DCMA?
