TIL: border searches of electronic devices
The border agent wouldn’t relent. He needed to access the device, he said, and had the authority to do so. He’d handed Bikkannavar a document titled “Inspection of Electronic Devices” when they first sat down, and Bikkannavar gave it a quick scan. The document claimed that CBP had the right to search “all persons, baggage, and merchandise arriving in, or departing from, the United States.” On the backside, in fine print at the bottom, there was a section with the heading, “Consequences of Failure to Provide Information.” The section said that giving up the information is “mandatory” and not cooperating could lead to the “detention and/or seizure” of the electronic device in question.
I didn't know the government can search your phone without a warrant when you return to the US.
