CHICAGO (AP) — Mayor Rahm Emanuel and Chicago’s new police superintendent are expected to announce Thursday that the city will immediately implement about a third of the recommendations made last week by a police accountability task force.

Emanuel’s office said in a statement late Wednesday that the city also is developing an action plan to address the remaining recommendations of the Task Force on Police Accountability.

The task force recommended sweeping changes in its April 13 report on the nation’s third-largest police force. It said Chicago police have alienated blacks and Hispanics for decades by using excessive force and honoring a code of silence. It found that the department does little to weed out problem officers and routine encounters unnecessarily turn deadly.

Emanuel established the panel late last year in response to an outcry over police shootings.

The mayor’s office said the reforms to be immediately implemented include strengthening the department’s accountability system so it can better hold officers responsible for wrongdoing and improving training so officers can better understand cultural difference.

The statement did not address what would happen to the city’s Independent Police Review Authority, or IPRA, which the task force said was “badly broken.” Emanuel has not ruled out doing away with IPRA.

Chicago’s new police chief, Eddie Johnson, has said the department was not waiting for recommendations from the task force or from a civil rights investigation by the U.S. Justice Department before making changes.
