Denver Police Intelligence Files and Police Records

In 1953, the Denver Police Department began to gather information on individuals and groups regarding activities that might pose a threat to public safety. The files came to be known as the Spy Files during the publicity surrounding an American Civil Liberties Union class action lawsuit in 2002. According to the lawsuit, as many as 3,200 individuals and 208 organizations had been targeted for intelligence gathering operations. These groups and individuals included not only criminal elements, but also peace activists, and education and human rights organizations. The lawsuit was settled in 2003, with the city revising its policies governing the gathering of this type of information.

Please note that for City and County of Denver Police Records, the Police Department has a retention period of 10 years for most reports made. For more serious crimes (i.e. homicides, sex assaults, etc.), those records are kept indefinitely. Additionally, their records can go as far back as 1920, but there is no guarantee they have all reports made or that they are still complete and intact. Current records have been digitized since 2008, and they will likely have more complete reports and records since then. It varies greatly the older the report is, and it is better to assess a record request on a case-by-case basis. Please contact them if you have any further questions or concerns.
