The ACLU of California, the ACLU, Asian Americans Advancing Justice - Asian Law Caucus, and the law firm Bingham McCutchen have filed a lawsuit challenging the federal government's Suspicious Activity Reporting program — a vast expansion of the federal government's domestic intelligence network. The SAR program supposedly facilitates the collection and sharing of information about activity that appears "suspicious," but in practice it targets First Amendment-protected activity, encourages racial and religious profiling, and violates federal law. The plaintiffs are five U.S. citizens whose information has been entered into counterterrorism databases for engaging in lawful conduct, and who have been subject to unwarranted law enforcement and scrutiny. The lawsuit was filed in July 2014 in the U.S. District Court for the Northern District of California. In March 2017, the District Court granted the government’s motion for summary judgment, upholding the SAR program’s standard for data collection. We are appealing that ruling to the Ninth Circuit Court of Appeals.
