If you were concerned that federal agents might play fast and loose with the Foreign Intelligence Surveillance Act's Section 702 while gathering data, your worries were well-founded. The Washington Post reports that Foreign Intelligence Surveillance Court Judge James Boasberg ruled the FBI and NSA committed multiple violations of either the law or privacy-minded court orders when collecting data from phone and tech companies. The opinion was issued in December 2019, but only published on September 4th. The violations were sometimes unintentional, but still meant investigators were overstepping measures meant to protect the privacy of US residents.
The FBI was supposed to honor a rule limiting to gathering data when it was “reasonably likely” to collect foreign intelligence info, but there were “widespread” instances where there focuses were US persons. FBI staff searched for info on a police officer job candidate, college students, possible sources, and a crime victim. It even sifted through the data of 16,000 people, only seven of which had possible links to crime or foreign intelligence info despite FBI claims to the contrary.
