Attorney General Eric Holder says "far more must be done to create enduring trust" between police and communities they serve, even as his Justice Department continues to investigate possible discriminatory police actions in Ferguson, Mo.
Civil rights lawyers at Justice working alongside FBI agents have also been examining whether white officer Darren Wilson intentionally violated the civil rights of 18-year-old Michael Brown, the unarmed black man he shot dead August 9.
Proving that Wilson, who was cleared Monday by a St. Louis County grand jury, violated federal criminal law will be difficult, DOJ veterans say.
But in the aftermath of the local grand jury announcement, Holder insisted the federal probe of the policeman is ongoing and independent of St. Louis prosecutors.
"And although federal civil rights law imposes a high legal bar in these types of cases we have resisted forming premature conclusions," Holder said.
Mediators from the Justice Department Community Relations Service have been on the ground in Ferguson trying to ease tensions since August. And the DOJ community-oriented policing unit has been trying to train local law enforcement to respect protesters and de-escalate tensions. Scattered violence and scenes of burning businesses in the area overnight Monday mean that work is far from complete.
Justice Department lawyers are making slow but steady progress on another facet of their task in Ferguson: investigating allegations of unconstitutional policing by law enforcement there.
Holder tipped his hand last month, publicly calling for "wholesale changes" in the Ferguson force. His DOJ investigators have opened more than two dozen investigations into biased policing tactics and patterns of excessive force in places from Albuquerque to New Orleans to Newark.
Such cases often end in lawsuits or court-enforceable agreements to change hiring, training and traffic stop actions.
Vanita Gupta, the acting leader of the civil rights division at Justice, said at a news conference last month that the goal of such cases is to "ensure that the city has an effective, accountable police department that controls crime, ensures respect for the Constitution, and earns the respect of the public it is charged with protecting."
The issue is personal for Holder, the country's first black attorney general. He told NPR earlier this year he wanted to keep working to forge connections between police and minority communities even after he retires from public service next year.
