As the nation's predominant law enforcement agency, the Federal Bureau of Investigation (FBI) has robust powers to peer into the lives of American citizens. But the FBI claims even broader authorities when acting in the nebulous realm of “domestic intelligence,” where its actions are largely hidden from public view and the procedural checks and balances that apply in criminal investigations are all but non-existent. The ACLU has exposed FBI abuse of its investigative authorities, through Freedom of Information Act lawsuits against FBI Joint Terrorism Task Forces, the FBI “racial and ethnic mapping” program, and the FBI eGuardian suspicious activity reporting program.
