The U.S. District Court for the District of Columbia has ruled that the search of a defendant’s laptop that was seized at the border violated his Fourth Amendment rights.  Investigators from the Department of Homeland Security seized the laptop of Korean businessman Jae Shik Kim at Los Angeles International Airport and later searched it to determine whether he had been involved in illegal exports of defense equipment to Iran.  The government later used data extracted from Kim’s laptop to indict him for violating U.S. economic sanctions and export controls.  The court granted Kim’s motion to suppress the evidence, rejecting the government’s arguments that it did not need any reasonable suspicion of criminal activity in order to conduct a border search and that, in any case, it had such suspicion here.  The court’s decision expressed deep misgivings about the whole “border search” doctrine, at least as applied to digital devices and the vast amount of personal information they may hold.  It also adopted a very narrow view of what constitutes “reasonable suspicion.”
