FBI's warrantless searches of Americans' data drop significantly following reforms.

The FBI's warrantless searches of U.S. citizens' electronic data under a surveillance program dropped by nearly 94% last year, according to an annual report by the Office of the Director of National Intelligence. The decline follows a series of major reforms instituted by the FBI, resulting in changes to FBI "systems, processes, and training relating to U.S. person queries." The reduction was not the goal of the reforms, and the number could increase again in future years. The report comes amid an intensifying debate in Congress about the reauthorization of legal authorities permitted under Section 702, which is due to expire at the end of this year.
