In 2010, the American Civil Liberties Union filed the lawsuit ACLU v. Alvarez against the State's Attorney of Cook County, Anita Alvarez, to block prosecution of ACLU staff for recording police officers performing their duties in public places, one of the group's long-standing monitoring missions [REF].
Alvarez and other state's attorneys, however, continued to pursue prosecutions against members of the general public who openly recorded on-duty police officers in public places [REF].
