"The Federal Bureau of Investigation made tens of
thousands of unauthorized searches related to US citizens between 2017
and 2018, a court ruled. The agency violated both the law that
authorized the surveillance program they used and the Fourth Amendment of the US Constitution.
The ruling was made in October 2018 by the Foreign Intelligence Surveillance Court (FISC), a secret government court responsible for reviewing and authorizing searches of foreign individuals inside and outside the US. It was just made public today."
