The FBI's Joint Terrorism Task Force
Working both inside and outside the courtroom, the ACLU of Colorado has been investigating and calling public attention to activities of the FBI’s Joint Terrorism Task (JTTF) that pose a threat to civil liberties.
There are over five dozen JTTFs around the country, including one at every FBI field office. They are staffed with FBI agents as well as detectives from local law enforcement agencies who are assigned to work full-time for the FBI. A detective from the Denver Police Department’s Intelligence Unit has been working full-time for the Denver JTTF since 1997. Since 2003, the Denver Police Department has assigned two full-time detectives to the JTTF. The Aurora Police Department, the Arapahoe County Sheriff's Office, the Jefferson County Sheriff's Department, and the Colorado State Patrol also contribute personnel to the Denver JTTF.
Follow the Chronology
During the litigation of the Denver Spy Files case, the ACLU of Colorado obtained documents that indicate that the JTTF has been collecting information about peaceful political activities that have nothing to do with terrorism. Read how the investigation unfolded.
