At a news conference on March 11, 2002, the ACLU of Colorado disclosed documents that revealed the existence of the Denver Police Department's "Spy Files." The documents showed that Denver police were monitoring and recording the peaceful protest activities of Denver-area residents and keeping files on the expressive activities of law-abiding advocacy organizations, in many cases falsely labeling them as "criminal extremist."

Later that month, the ACLU filed this class action lawsuit on behalf of three organizations and three individuals who were the subjects of "Spy Files."  After extensive discovery, Denver agreed to a settlement the following year that restricted political spying and provided multiple additional changes in policy and practice.
