Denver police intelligence bureau officers may have conducted background checks for private companies and spied on journalists, according to a federal lawsuit. Police also kept files on groups and individuals they labeled "criminal extremists" [3] including the American Friends Service Committee (AFSC), an 85-year old pacifist Quaker group that won the Nobel Peace Prize for its advocacy of non-violent social change, and the Chiapas Coalition, which supports the struggle of indigenous persons in the Mexican state of Chiapas. Individuals whose names appeared in police files include Sister Antonio Anthony, a 73-year old Franciscan nun.
