The American Civil Liberties Union of Colorado is suing Denver police, seeking records of internal investigations stemming from the so-called "Spy Files" controversy of 2002 and 2003.
The ACLU filed the lawsuit this morning on its own behalf, and that of longtime political activists Stephen and Vicki Nash of Denver.
It's the sixth time in recent years the ACLU has filed suit in response to police claims that disclosing the records would harm the public interest.
The ACLU says the Nashes learned in 2002 that Denver police were monitoring their activities, and keeping files on their associations.
Police agreed as part of a separate lawsuit settlement in 2003 to keep files only when there's reasonable suspicion that someone is involved in a crime.
