EFF: The Bill of Rights at the Border: Fourth Amendment Limits on Searching Your Data and Devices by Stephanie Lacambra:
More than 325,000 people enter the United States via airports every day, with hundreds of thousands more crossing by land at the borders. Not only is that a lot of people, it’s also a lot of computers, smartphones, and tablets riding along in our pockets, bags, and trunks. Unfortunately, the Fourth Amendment protections we enjoy inside the U.S. for our devices aren’t always as strong when we’re crossing borders—and the Department of Homeland Security takes advantage of it.
