From HuffingtonPost:
The Better Government Association has filed a lawsuit against the Chicago Police Department in an effort to compel the release of plainclothes officer deployment data the department has refused to make public, citing safety concerns to circumvent Freedom of Information Act (FOIA) transparency requirements.
The BGA requested documents showing where tactical units were deployed earlier this year, part of an effort to investigate officer placement and evaluate how often tactical units were operating outside their assigned districts, according to a press release issued by the watchdog agency.
