The ACLU has a point on this one…

The ACLU, the New York Civil Liberties Union and the National Association of Criminal Defense Lawyers have filed a lawsuit challenging the Department of Homeland Security’s (DHS) policy of searching, copying and detaining travelers’ laptops, cell phones and other electronic devices at the border, even when DHS has no reason to believe a search would reveal wrongdoing.

The DHS suspicionless search policy applies to both U.S. citizens and non-U.S. citizens, and subjects travelers to the possibility of having their most personal information — such as financial records, family photographs and lists of Web sites visited — reviewed by government agents. Between October 1, 2008 and June 2, 2010, over 6,500 people — nearly 3,000 of them U.S. citizens — were subjected to a search of their electronic devices as they crossed U.S. borders. DHS claims it has the right to conduct these invasive searches whenever it likes, to whomever it likes, and without having any individualized suspicion.
