The report, remarkably, shows that the government obtained just one order last year under Section 702 of FISA—which allows for bulk collection of data on foreigners—and that this one order covered 89,138 targets. But, as the report notes, “target” can refer to “an individual person, a group, an organization composed of multiple individuals or a foreign power that possesses or is likely to communicate foreign intelligence information.”
Furthermore, Section 702 orders are actually certificates issued by the FISA Court that can cover surveillance of an entire facility. And since, as the government points out in its report, the government cannot know how many people use a facility, the figure only “reflects an estimate of the number of known users of particular facilities (sometimes referred to as selectors) subject to intelligence collection under those Certifications,” the report notes.
