With protesters thronging the streets of Chicago demanding police accountability and clamoring for the resignation of Mayor Rahm Emanuel, the city's police union is frantically trying to destroy decades of records documenting police misconduct. As is always the case, the Fraternal Order of Police (FOP) sees "officer safety" as the highest priority – including protection from legal accountability.

"I protect all my members, and I will continue to do that," Dean Angelo, president of the Chicago FOP, explained to CNN.

An injunction filed by the FOP insists that preserving those records violates Section 8.4 of its bargaining agreement with the City of Chicago.
