At least as far as a forensic search (more than just turning it on and having a quick look) goes. In 2012, Homeland Security was conducting an investigation based on a jailhouse informant who said that Jae Shik Kim was involved in a 2008 crime. So, they did some investigating, found incriminating details, and applied for a search warrant. No, of course not, that would be too much work. Instead, they waited until Mr. Kim was crossing the border on an international flight and seized his laptop with no warrant an no more evidence than the tip, under the Obama administration’s “I do what I want!” policy regarding searching electronic devices at the border (scroll down to item 5.1.2 for what CBP thinks is lawful).
U.S. District Judge Amy B. Jackson has finally issued the government a long overdue smack-down in this regard. While her ruling is based on the particularly egregious circumstances of this case (waiting for someone to leave in order to get around a warrant, seizing the laptop without searching it and transporting it to be imaged and forensically analyzed, the flimsy tip, and the lack of any allegation of a current crime), she resoundingly rejects CBP’s assertion that it needs no suspicion to do whatever it wants at the border regarding digital devices.
Good on you, Ms. Jackson.
