The NSA has published 12 years of quarterly reports that show the agency may have violated the law for more than a decade.
The reports were created for the President's Intelligence Oversight Board between 2001 and mid-2013.
PBS explains that the report details that the NSA continually used unauthorized signals for intelligence gathering that includes phone call metadata. Details of intentional misuse are present throughout the reports.
Most of the reports are redacted.
Bloomberg writes that the NSA's inspector general detailed 12 cases of intentional misuse by intelligence authorities in that time period. Some of its analysts deliberately ignored restrictions on their authority to spy on Americans.
Patrick C. Toomey, staff attorney with the ACLU’s National Security Project, writes about the NSA's misuse of intelligence gathering.
“The government conducts sweeping surveillance under this authority -— surveillance that increasingly puts Americans’ data in the hands of the NSA,” Toomey writes.
“Despite that fact, this spying is conducted almost entirely in secret and without legislative or judicial oversight,” he said.
