The ACLU and the Electronic Frontier Foundation filed an amicus brief arguing that when the government wants to use invasive surveillance technology, it has an obligation to explain to the court basic information about the technology, such as its impact on innocent third parties. This is necessary to ensure that courts can perform their constitutional function of ensuring that the search does not violate the Fourth Amendment. Unfortunately, today’s decision trivializes the intrusive nature of electronic searches and potentially opens the door to troubling government misuse of new technology.
