The Foreign Intelligence Surveillance Act (FISA) allows for surveillance of electronic communications made by foreign entities and individuals, with minimal oversight and transparency. Synonyms for FISA include Foreign Intelligence Surveillance Act of 1978 (FISAA), Foreign Intelligence Surveillance Act Amendments Act of 2008 (FISAAA), and Foreign Intelligence Surveillance Court (FISC). FISA has come under scrutiny for its potential to violate civil liberties and infringe on privacy rights. Critics argue that FISA has been used to surveil innocent Americans without proper justification or oversight. Despite its controversial history, FISA remains an essential tool for national security agencies to monitor potential threats and gather valuable intelligence.
