A commitment to community policing is one of the key reforms the U.S. Department of Justice expects from the Cleveland police department after issuing a report that says officers too often use excessive force and violate people's civil rights.

Deputy Attorney General Vanita Gupta said at a news conference Thursday led by Attorney General Eric Holder that accountability and community policing make the job of delivering police services easier and safer.

The DOJ spent 18 months investigating use of force policies in Cleveland after a series of well-publicized incidents, including the killing of two unarmed civilians in a hail of police gunfire after a high-speed chase.
