The U.S. Intelligence Community has illegally spied on Americans for many years. The FISA court monitors those agencies to ensure they don't violate the Constitution but the court has been repeatedly misled. That's the focus of Episode #12.
The Foreign Intelligence Surveillance Act (FISA) created the FISA Court. The act is designed to catch spies and terrorists without violating the U.S. Constitution. The authority to conduct surveillance is divided into two categories.
The video report cites three FISA Court opinions dating back to 2011. You'll find links to those opinions below. Be advised. They are not easy reads. They are loaded with jargon and redactions. So, they do not read like a spy novel.
