The ACLU of Colorado is the state’s oldest and largest civil rights organization with a mission to protect, defend and extend the civil rights and civil liberties of all people in Colorado through litigation, education and advocacy. They are part of the national American Civil Liberties Union coalition, which is the nation's largest collective dedicated exclusively to ensuring the rights and liberties afforded to all Americans by the United States Constitution. ACLU's legal department writes letters, talks to government agencies and, if necessary, files lawsuits on behalf of clients whose rights have been violated and advocates for rational laws that protect people’s rights and liberties. The ACLU engages and informs Coloradans through public forums on current civil liberties issues, “Know Your Rights” training, rallies and media events.
